SLG Comms 2.2.1 released

Another new version. This one hosts a lot of performance enhancements.

here's the change log

v2.2.1
- Improved the displaymessage function when it's supposed to stop script execution.
- Overhauled the complete TeamSpeak server data parser code to improve performance.
- Checked and, when possible, adjusted all condition statements to be stricter.
- Updated install.php to support updates after v2.2.0 as the old version number wasn't retrieved if you installed SLG Comms with database support enabled.
- Enhanced install.php in upgrade mode where possible to be less confusing.
- Improved the template process a tiny bit. Though it's still problematic when viewing TeamSpeak and / or Ventrilo servers which have unusually large amount of channels and clients (Large meaning more then 400 channels).
- Rearranged some language items to possibly speed up the template process for the TeamSpeak and Ventrilo templates.
- Fixed a small bug which concerns the caching of data. This was specifically causing problems for the TeamSpeak server data parser.
- Fixed a bug where TeamSpeak command errors weren't detected correctly.
- DEBUG mode now also displays the processing time for the template engine.
- DEBUG mode now also displays the time it took to retrieve the live server data.
- Added some validity checks on the custom ip:port field.
- Fixed the displayal of the "Retrieved data status" which sometimes displayed incorrect values.
- Changed the moment where live server data is saved for caching.
- Fixed a glitch in the TeamSpeak server parser concerning clients nickname and loginname.
- Updated the TeamSpeak and Ventrilo server data parser to be more secure against tampering.
- Improved the DB classes.
- Fixed a notice level error with the "Page refresh timer" variable in header.inc.php
- Fixed a bug in the MySQLi DB class (mysql41.inc.php) concerning the timecount class calls.
- Added "Recording" and "Voice Request" status to the info behind the name of the clients.
- Removed the "breakdown_rights" function as i've implemented a faster way for calculating the rights of clients and channels.
- Fixed a bug in the TeamSpeak function which detenmines the flags that should be displayed. It sometimes displayed the Auto-Voice flag while it should display the Auto-Op and vice versa.
- Finetuned the channel and client sorting functions a bit.
- Improved the TeamSpeak error managing a bit.
