SLG Comms 2.2.2 released

There was a relatively serious bug in the TeamSpeak server parser which required a bugfix release.

Changelog:
v2.2.2
- Fixed a glitch in install.php when selecting the wrong installation type when you're upgrading an existing installation of SLG Comms.
- Added a extra check whether the queryport for TeamSpeak is actually a port number.
- Improved ip:port checker
- Automatically select the right install type and hide the language and template options incase of updating an old version of SLG Comms.
- Fixed a whitespace problem in the custom ip:port field
- A number of small tweaks to the TeamSpeak channel / client looping process
- Fixed a bug in the TeamSpeak server parser which could cause NOTICE and WARNING level errors to be generated.
- Removed version number from the default Page title field upon a new installation of SLG Comms as this number might be confusing when updating SLG Comms.
