Updated several files to split up phrases like "Your lock has expired. Please try again!" into "Your lock has expiredx" and "Please try again!"

Note: Since I'm not sure if that's all (replacing %s %s with %1$s %2$s) which is necessary to make this work, I'm sorry in advance for a potential "bad commit".

As already written on Crowdin, in German the order is wrong, so my suggestion is to make it possible to change the order by transforming "%s %s" to "%1$s and %2$s".
Format in English: Successfully assigned 4 selected tasks
Needed German: Successfully 4 selected tasks assigned

Fix translation so it makes sense.
Before: "Unable to change status for 2 any of the selected tickets" - sounds wired
After: "Unable to change status of 2 selected tickets" - sounds correct and fits into the rest of the translation scheme ;)

This pass also makes a stride at adding correct punctuation and making error
phrases consistent.

This is my attempt at removing similar texts from the translator work load.
It also makes an attempt at dropping some misspelled words and works toward
standardizing some phrases.

Make tasks actions icon based buttons
Fix task assignment issue

Filter assignees based on selected tickets department setting.

Filter members based on department's assignment restriction when building a
list of assignees.

ClaimForm extends AssignmentForm and hides assignees selection. Claimant is
still given the opportunity to log an optional internal note as to why
they're claiming the ticket in question.

Let the object have full control the list of possible assignees

Due to MySQL FULLTEXT min-word-lenn requirements (which various from
installation to installation), fulltext-based searches require at least two
characters.

Otherwise we might end up with a search term like '"some junk"*' which is
invalid.

This time, use full-text for user and ticket lookup boxes, and drop the
full-table scans from the ticket basic search page. Auto promote searches to
wildcard searches when searching with the user-supplied input yields no
results.

Also, fix submission without a lock and locks are disabled

- Adds mass assign, transfer to ticket queues
- Retire inline forms for ticket assignment and transfer

- Tickets cannot be closed when an open ticket exists
- Tickets/Tasks cannot be closed when required for close fields are missing
data
- Add isCloseable routine to ticket/task classes

Initially, include support only for Gravatar

The setting is no longer ticket thread specific. Disabling html is now
system wide setting for disable-able textarea widgets as well as email
correspondence.

This patch removes several of the internal notes posted to a ticket for
various events and replaces them with events added to a threads event chain.
The emails are still sent out as they previously were, but internal notes
are only added to the thread if an agent actually specified comments.

Move collaboration implementation to thread level

Reset field content when building a new form

Also, add warning popup when lock is about to expire and allow the user to
attempt to renew the lock. Also, connect the keyup callback for redactor to
the autoLock.handleEvent for greater update of the lock, and also deadband
the lock to every 10 seconds.
