issue: FAQ Return Errors

This addresses an issue reported on the Forum where creating a new FAQ and
not filling out required information returns the correct error but returns
the incorrect template (FAQ View Template). This is due to the check for an
FAQ when determining the template to return. This adds a check for the FAQ
ID to determine if it’s an actual FAQ or just a model instance.

issue: FAQ Search Results

issue: Canned Response Variables

This addresses an issue reported on the forum where searching for a keyword
in FAQ search brings back more results than it should. This is due to the
format of the query selecting the results, essentially, the `WHERE NOT`
statement is not properly formatted so the `OR` statements take precedence
over the `WHERE NOT` causing non-public results to be shown to the client.
The `WHERE NOT` statement contains the bit to select from only public faqs
and since the `OR` takes precedence it will return the non-public results
too.

issue: PHP 7.2 Ticket Status

This addresses issue 4756 where the `%{recipient.ticket_link}` variable is
not being replaced when the canned response is loaded in the reply box; all
other link variables work. This is due to the recipient object not being
passed to the variableReplacer which means the ticket_link is not available.
This adds the recipient object to the variableReplacer so the ticket_link
variable is properly replaced like the others on load.

This addresses issue 4716 where updating a Ticket Status throws a fatal
error of "Too few arguments" when using PHP 7.2. This is due to `$errors`
not being passed to the `update()` function causing PHP 7.2 to freak out.
This creates an `$errors` array and passes it to `update()` so PHP 7.2 is
happy and we are all happy. :)

Minor typo fix

issue: No Save Button On Quicknotes

issue: Upgrader Wrong Guide Link

This addresses issue 4738 where the Upgrade and Migration Guide link is
incorrect. This updates the link to the new Documentation site.

This addresses issue 4725 where there is no save button when editing a quick
note. This is due to the jQuery update which changed how a few things work
with redactor.

changelog: 1.10.5

This adds the changelog for 1.10.5 maintenance release

i18n: Fix build language packs for the 1.10.x branch

issue: Translation Flags Not Clickable

This addresses an issue where the second row of translation flags are not
clickable when editing a Form with 23+ languages installed. This adds a
`height` of "auto" so that the entire div fits the flags’ surface area,
making them clickable again.

jq: Update To jQuery-3.3.1

This pull request is wayyyy overdue. This updates jQuery and all related
files to the latest jQuery release (3.3.1). This also adds a new script
called jQuery-Migrate that maintains older functions needed for a few things
(eg. `filedrop.field.js`).

Improve the Staff login

Issue: Tasks Within Tickets

issue: Hide Task Loading Overlay

This addresses an issue where the Loading overlay on Tasks will not
disappear after the request was submitted. This adds two lines to first hide
the "Loading" modal and then toggle the overlay.

issue: Dashboard Export Period

This commit addresses issues we had with viewing Task(s) within a Ticket:

1. When viewing the table of all Tasks on a Ticket, the Options dropdown should only allow the Agent to Reopen or Close the Tasks based on the status of the Tasks.
Ex: If there is only 1 Open Task, you should only see the 'Close' Option
    If there are 2 Closed Tasks, you should only see the 'Reopen' Option
    If there are multiple Tasks in which some are Open and some are Closed, you should see both the 'Reopen' and 'Close' options

2. When viewing an individual Task within a Ticket, the status options were the opposite of what they should have been. Now, if the Task is Open, the Agent will see the option to 'Close' the Task. If the Task is Closded, the Agent will see the option to 'Reopen' the Task.

This addresses an issue where exporting statistics via the dashboard within
a certain timeframe (eg. 07/01/2018 -> One Quarter) will always export the
statistics from the selected date up to today. This is due to the Period
option always being set to "Up to today" when the Export button is clicked
which in return exports the stats from the selected start date to today.
This adds JS to set the period the Agent selects so the Export will return
the stats from the selected date to the selected period.

- Follow the same pattern that the client login https://github.com/pitbulk/osTicket/blob/develop/login.php#L48 . Otherwise StaffAuthenticationBackend that receives a POST are not possible.
- Refresh $msg with the value stored in session if the StaffAuthenticationBackend backend defines it, otherwise the initial "Authentication Required" is prompted.

oops: Remove DST From User Update

This addresses an issue where Users updating their profile will throw an SQL
error in the system logs. This is due to a line of code trying to set a
value for the `dst` column which no longer exists as of `1.10.0`.

issue: Dupe Page Requests Fix

This addresses an issue with pull 4472 where disabling the Submit button
does not submit the Input value for the button. This affects the
installation of plugins, where the Install Path is not sent therefore the
plugin is not installed. This clones the original submit button, hides it,
then displays a dummy disabled Submit button which will submit the value and
prevent dupe posts.
