Fixed the issue where it would whine about the empty string and stuff.. still some shit left to deal with...

Known issues:

*	If user has got +v while got +o and gets deopped,
 	it doesnt remember the previous mode and sets zero prefix

*	Names list is not channel specific yet :(

*	The bot cannot "see" itself, so bot given modes arent included to prefix

* 	Error handling and logging is still absent

*	'list out of range' on PART, QUIT doesn't clear the nicklist

*	If someone parts the channel, it cannot get the nick prefix straight...
	We are using there self.get_nick() to have just any nick in place
