XenTrader Unsupported

Until this gets the complete re-write it needs, i'm marking it as unsupported and no guarantees it will work. (though it currently does).

The following is a list of changes from XenTrader 2.1.0

• Feedback threads for a user are now selected if the user has posted in a thread instead of starting the thread
• The ACP will now properly show an error instead of a heap of raw HTML
• Fixed retain_keys undefined index when importing
• Report handlers not registered fixed, fixes reporting feedback
• Fixed uninstall errors
• Fixed xentrader index display errors in some browsers
• Feedback score added to member card
• Added missing phrase xentrader_neutral_feedback
