slimCat "Caracal" r13

-fixed an issue where channel updates and invites were wrongly supressed
(introduced in r12)
-sort of added banlist. Doesn't work correctly right now, but 95% of the
work for it is done
-moved client IDs to a compile-time constant instead of having them
defined all over the program redundantly
-added an update checker (doesn't auto-update, just a notification)
-added signal strength bars to give a rough idea as to how stable the
connection is
