down for everyone plugin
Enable isup plugin
Print message on import/reload fail
remove useless pass
Created a 'internal command table' to have easier lookup for internal
commands (e.g. help, info)
Improve plugin manager

The plugin manager should detect if the message is a private message and
not create a new 'channel' for that user.

Creation of networks / channels for the plugin manager is now done when
connecting / joining a network / channel
Remove the 'channel_is_user' checking crap by a simple is_channel test
Let isup check the amount of arguments passed
Move parser.quote_plus into core/tools and do some cleanup on plugins
Remove whitespace
