Address Security Issues On #4331

issue: Auto-Assignment Log

issue: Ticket Lock On Disable

issue: User Import No Email

This addresses an issue where disabling Ticket Locks but setting a time
for the Lock Timeout will always throw a "lock required" error. This adds
a check to see if locks are enabled AND there is a time set. If locks are
disabled it will not throw the error.

This addresses issue 4329 where you can import a User with no email
address via CSV file. Once the User is added and you try to update them
with an email address it fails due to no default email. This updates the
check for email address from `!isset()` to `empty()` which will correctly
check for empty string.

issue: CLI Deploy Missing Bootstrap

issue: Language Pack Locale Mismatch

UI changes to make it more user friendly

Make it a utility class for parsing an email address. Relies on PEAR to
parse RFC822 compliant email.

This commit adds ability to send and email to multiple recipients with
auto-detection of TO/CC/BCC  (based on user class)

This addresses an issue where osTicket did not ensure associated items exist
before saving to the database. This also addresses an issue where the Parent
Topic error was not displayed on page.

It may be possible to steal or manipulate customer session and cookies,
which might be used to impersonate a legitimate user, allowing the hacker to
view or alter user records, and to perform transactions as that user.
Sanitation of hazardous characters was not performed correctly on user
input.

osTicket did not properly sanitize array values in `Format::htmlchars()`.
Some values in the Admin Interface were not properly sanitized and returned
to the response.

Final Additions For v1.11

- Separate 'message' and 'response' variables on New Ticket Notice so they can be styles separately
- Add Thread Event state for 'released'
- Add 'refer' and 'release' permissions to the Role table
- Update install-mysql
- Update patch file name
- Update core.sig
- Set flags in correct place for class.depts.php
- Make sure when opening Ticket, User stays selected if submitted with errors
- Make sure Mail Box Protocol saves correctly when configuring emails

This commit fixes a bug where Public User Registration always resulted in creating a new User. Now, if a User goes to register an Account and their email already matches a User in the system, we will register the existing User. To set the registration method, go to:
Admin Panel | Settings | Users | Registration Method

For thread events, the referral state was spelled as 'reffered' instead of 'referred'. This needed to be changed to save to the database correctly. A new patch file has been added to correct the schema signature.

For new tickets, hide the Ticket Notice dropdown if the 'New Ticket by Agent' autoresponse is disabled since no response will be sent

feature: Manage Referrals Role Permission

feature: Release Role Permission

This feature adds a new Role permission called Release. This permission
(if Enabled) allows an Agent to release ticket assignment. This permission
is configurable for each and every Role in the helpdesk. This also keeps
current functionality where Department Managers do not need the Role
Permission in order to release tickets. In addition to the permission,
this feature adds a new Release modal giving the option to choose who to
release assignment from (Agent/Team/Both). This also adds a comment box to
the release modal to optionally enter a reason for releasing assignment.
Lastly, this adds a Release Thread Event so an event is logged showing who
released who’s assignment.

This addresses issue 4322 where deploying via CLI is missing
`bootstrap.php`. This is due to the `get_include_dir()` function that
tries to include a file from the destination which doesn’t exist yet,
causing a fatal error. This updates the function to use `$this->source`
instead of `$this->destination` to correctly find and include
`bootstrap.php`.

This feature adds a new Role permission called Manage Referrals. This
permission allows Agents to Manage Ticket Referrals. This permission
is configurable for each and every Role in the helpdesk.
