Update game countdown message
Update tests to craftbukkit 1.6_R1
Fix player ranking criteria
Use 'points' instead of 'score' column in results
Use scoreboard prefixes in chat box for team names

Updates the weighting count function to ignore colour codes, so can
include colour codes when aligning text.
Use eliminated order to rank elimination players

- /ro scores will not show eliminated entities during a game, but will
  if the game isn't running.
- /ro scores full will always show all entities.
Initialise match countdown flag

Fixes error message when '/ro stop' called before game started.
Don't try to send messages to offline players
Don't count offline players in default chan count

Everyone who joins the default chan is kept their for the duration of
the plugin, so many won't have actively joined. An online member count
is more appropriate.
Use display names in chat and team chat commands

Also, set default channel addme setting to False to keep channel
noise down.
Tidy help commands

- Move /ro helplist to /ro help list
- Move /ro usage to /ro help usage
- Support /ro help <cmd> as well as /ro <cmd> help
Carry the 'addme' setting over between games

As it's essentially a channel command, it's just presented to the user
as a game command.
No need to shorten usernames

As they're limited to 16 characters, so won't reach the end of any
results columns.
