Fix cases where first item added via addSubMenu got deleted.

Move ticket status change to unified backend.

Only cache results for ALL items

Turns out including a PHP file in a PHAR file is not cacheable by APC. This
patch adds APC stash support to the translation loading phase, if supported.

request. Most of the savings is in the PHAR file processing time (signature
verification), which is avoided if the translation can be loaded from APC.
