- Save Filter Actions at the top of Filter::save
- Validate the Filter Actions before commiting the save

This is done to fix the issue where Depts/HT's said 'Unchanged' when initially saved. Now their configuration is set correctly before doing additional validations for active depts/hts

- change recipient name vars to 'Collaborator' in tmpls if ticket user isn't a recipient
- for templates going to Bcc'd Collaborators, account for all name format variables that could be used
- new function getNameFormats returns an array of all name formats in templates for staff.name.* or recipient.name.*
- other minor cc/bcc fixes

This fix uses 'filter' instead of 'findFirst' for finding Dept and Team referrals since the __in operator is not included in the evaluate function that was being called when using 'findFirst'

- function isReopenable needed to check for topic
- getHelpTopics for inline edit needed to include name of disabled Topic if selected
- getHelpTopics for dashboard needed to include disabled/archived Topics

Commit 3944b51d added ability to archive help topics and departments but
failed to port changes default data (yaml files) loaded on install.

This commits adds the correct bits to flags field for both help topics and
departments. It also removes retired 'isactive' field for help topics.

This commits adds ability for agents to configure public queues.

* Customize Columns
* Set default sort & quick filter
* Add supplemental filters (criteria)

To support above features this commit also addresses confusing Advanced
Search UI to make it intuitive when dealing with a Saved Queue vs. Saved
Search vs. Adhoc Search

This commit adds var_dump test along with a few enhancements on the test
script.

Only ignore visibility constraints on private "searches" when staff is allowed to search the backend.
Access control is strictly imposed on ALL queues including inherited private sub-queues.

This addresses an issue where you can exploit XSS in the help-topic AJAX
request. This adds a check for a refferal URL and if none it will return
a 403 Forbidden Response.

This addresses an issue where the CSRF Token is displayed in the URL
when you preform a search in the Users Tab. This removes the token from the
request which removes it from the URL.

Updated to fix typo "information" on line 36

* Dont't fetch templates while in a loop
* Tidy up the code

Commit c4579277 introduced an extra administrative security feature to
restrict files access to signed in users only, even  if a user has a valid
& signed download URL. The feature, however, did not take into account
public images & files associated with FAQs and pages such as
landing/thank-you pages.

This commit addresses the shortcoming by adding a reference ID (attachment ID)
to the download/access URL, that can be used to deduce the model/object type
that the file request is associated with. The technique will allow us in the
future to enforce ACL at the file level depending on privacy settings and
the security clearance of the user (agent).

Account for the possibility of agents being deleted

This commit adds user's account username as one of the field to scan on quick lookup;

Make selection fields play well with Advanced Search

Commit 5be0de0d introduced the idea of moving-up old saved searches to make
room for Custom Queues but failed to account for cases where the system
has more than 30 saved searches.

This commit addresses the issue by just re-inserting the old records after
queues are imported. It also adds validates & reformat the search criteria
to make the expected format.

This updates the Phone Field name back to `phone` and changes the flags
to make the variable name non-editable. This also adds a check for the
phone field on the User Form and if one exists adds it to the search.
