issue: Client Side Thread Entries

Conflicts:
	js/redactor-osticket.js

This addresses an issue where the client side thread entries are all grouped
within the same div. This pushes all grouped entries to one side of the page
making them illegible.

This commit addresses an issue where saved searches were not being ported to
SavedQueues on 1.10.x upgrade to 1.11.x

issue: jQuery Sortable Redactor

Web Portal Fixes:

collab: @localhost Mailer Error

- Add space between column headers and sort arrow
- Fix sorting by 'Subject' column
- Fix redactor issues with 'Reset' button
	- Make sure text within redactor is cleared correctly
	- Make sure we don't keep attachments if Reset
- Make sure redactor is reinitialized where needed

This addresses issue 4372 where any Redactor text box within jQuery sortable
is not clickable. This is due to Redactor not being an actual input field,
rather a div, so sortable doesn’t see it as an input.

This addresses issue 4370 where Users responding to tickets via Client
Portal triggers a “Failed to add recipient: @localhost” Mailer Error in the
osTicket Logs. This is due to the `notifyCollaborators()` function that
lacks a check for an empty mailing list.

This address issue 4366 where sending a User a password reset email throws a
fatal error of "object of type EmailAddress cannot be used as an array".
This adds a switch case for EmailAddress to get the User's email address as
a string not an object.

This addresses an issue introduced with 4332 where the deploy CLI breaks
upon deploying to an existing location. This checks to see if there is a
bootstrap file in the destination first and if so it uses that one if not
uses the source.

This addresses an issue on the forums where osTicket does not add the proper
values to any custom choices field template variable. This adds an `asVar()`
function to `class ChoiceField` so we can return the proper values for the
template variables.

This addresses an issue where client side column sorting does not work at
all. This is due to the if/else statement that checks for a REQUEST sort
order and if the REQUEST sort order matches an `$orderWays` array value. The
if statement returns TRUE for DESC and sets the sort order to DESC as it
equals '-' (a dash) but ASC equals '' (an empty string) so it returns FALSE
which fails-over to the else statement setting the sort order to DESC. In
addition, this adds sorting icons the the column headers to make it more
obvious they are sortable.

This addresses issue 4339 where the installer footer references the wrong
copyright date.

This addresses an issue introduced with a3d896c8 where TextThreadEntryBodies
are not keeping their new line characters causing the email format to appear
wonky. This balances the entry and then htmlchars it to ensure no XSS.

mailer: EmailAddress Object as Array

This address issue 4366 where sending a User a password reset email throws a
fatal error of "object of type EmailAddress cannot be used as an array".
This adds a switch case for EmailAddress to get the User's email address as
a string not an object.

issue: CLI Deploy Missing Bootstrap Fix

issue: ChoiceField Template Variable

issue: Client Side Column Sorting

issue: IE White Screen Of Death

Typo fix, unneeded semicolon

This addresses an issue introduced with 4332 where the deploy CLI breaks
upon deploying to an existing location. This checks to see if there is a
bootstrap file in the destination first and if so it uses that one if not
uses the source.

This addresses an issue on the forums where clicking to view the ticket as
an Agent in IE 11 throws a white screen of death. This is due to the
shorthand javascript arrow functions in `include/staff/ticket-view.inc.php`.

 Collaborator Fixes

- Fix for ‘creating default object from empty value’ message
- Add collaborators in the Ticket::create function instead of Ticket::open so that we can getRecipients in postMessage function
- Add relevant thread_entry_recipients in postMessage function for front end tickets (scp or Web Portal)

Note: This in turn fixes Issue #4354

This commit puts the recipient icon (for one recipient or multiple) on Thread Entries created by Users. It also stores email recipients so you can view them in the Thread Entry Actions.

For Emails:
All recipients in the email are tracked

For front end entries:
All recipients who received an alert are tracked

values to any custom choices field template variable. This adds an `asVar()`
function to `class ChoiceField` so we can return the proper values for the
