[Matze B. <ma...@br...>]

Hi,

as noone is in irc right now who could commit my fixes, I send them here. 
The attached files does the following:

-fixes fast music being replayed again and again
-fixes time being displayed negatively when tux dies because of timeout
-fixes exploding bombs that hit mrbomb, so that the hit mrbomb now really 
 transform into a bomb
-updates the TODO file

Greetings,
