Added /wsqlcheck command to check sql connection status
Added /wsqldisconnect command to manually disconnect sql server
Added /sqlconnect command to manually connect sql server
Added a scheduled task that runs every 36,000 game ticks (approximately every half hour) to make sure the sql server has not booted the minecraft server from the database due to inactivity (it reconnects automatically if it detects that it has)
Bug fixes with SQL handler code that may have caused the server to think it was connected to a database when it actually wasn't
