Big code refactoring, bug fixing

NotEnoughClasses moved into a seperate file, will now be reloaded
correctly on a command reload. NEMP Thread and event will now be killed
on command reload. Replaced writeQueue with proper logging. Replaced
self.sendChatMessage with self.sendMessage. Updated the 'about'
information. Added status command (shows if nemp is running or not, and
in which channel) and disabledmods command (shows which mods are
disabled right now). Removed one of the two time events. Thread now runs
continuously, sleeping for some time depending on the time set when
starting nemp. Added a few smaller bugfixes, e.g. replaced help["bla"]
with helpDict["bla"].
