DeathControl

• adapted to the new event handling system (this makes the plugin 1.1-R5 ready)
• recoded most of the death handling part - this doesn't really affect functionality
• added fully configurable experience handling; check Configuration for more information
• implemented configurable timer before stored items are dropped when the player disconnects; check Configuration for more information
• tweaked logging-level to influent all possibly unimportant logs; also moved from number-based levels to word-based

Vault support didn't finish in time, sorry.
