Added MySQLWrapper. This class does a lot of good things.

It handles all methods with MySQL
(Still needs to be thread-safe) soon.
Updated to latest version of Bukkit
Support for MySQLWrapper

getLocalTime() & getGlobalTime()
Removed method part. This is not needed anymore as Autorank will sync
between servers now! Happy us!
Added /ar gcheck and changed /ar check to getLocalTime().

* /ar gcheck will get your global time. It is sum of all minutes played
on every server.
* /ar check will only show the local time via getLocalTime()
* Updated /ar help pages
Added .isClosed() method to check if the connection is closed or still
alive.
Support for the new getLocalTime() and getGlobalTime()
The PlayTimes class does not handle MySQL queries now. This is handed
over to the MySQLWrapper class for an organised look.
Also update global time when a check occurs.
Set INTERVAL_MINUTES back to normal.
Updated build number (to Beta 2.5)
