Updated build path to spigot-1.7.9-R0.1-SNAPSHOT
Changed build path to from spigot to
craftbukkit-1.7.9-R0.1-20140424.033947-16
Changed from usernames to UUIDs

Warning: No converter implemented yet for existing config files!
Updated version number to 0.1.1
Added broadcast-failed-logins option, default is true
Fixed an error with invitations by console... it obviously doesn't have
an uuid!

Also changed the colors of the kick/disconnect/whitelist messages.
Fixed an error in the authors syntax
Changed plugin name from "Invitation[0x20]Only" to "InvitationOnly"
because the use of the space-character (0x20) in its name is discouraged
by bukkit.
Added some comments
Added ability to save the name of a player in the users.yml and update
it on the (atempted) join of an invited player or member.
Added import of whitelisted players as members when there is no
users.yml (aka on the first plugin start)
Cleaning up. Damn whitespaces!
Added functionality which automaticly adds to and removes a player from
the whitelist when he becomes/ceases to be a member.
Fixed that invited players didn't get kicked if no OP/member is online
anymore!
