Major schedules & DB refactor

Browse Source 
Refactored many calls for TimerManager's schedules throughout the source.
Switched all tables using MyISAM to InnoDB: on a multi-threaded environment such as this, table-locking is an instant no-no, and other gains MyISAM would have over InnoDB are minimal.
Altered getConnection() to properly throw an exception (good practice!) in case of no available connection instead of a mere null.
