Titan [ClockOffsetFix] v1.5.3

Fixes the Titan Panel Clock so that its offset is stored per server not per character.

This way when you start a new character the time offset is already correct.

This also fixes a time offset bug if you have characters with he same name on different servers.

Added optional dependency on GroupCalendar. If you have GroupCalendar installed, the time offset is automatically calculated and set. Your Titan clock will always have the correct local time. This calculation is done every time you zone, and thus also provides correct times when in cross realm battle grounds where the time offset is often different than what you have set.
