-Unified the in-game and ico chat system. They now share the same irc/wow like commands. Full autocomplete with tab/shift-tab. Autocomplete will attempt to either complete the name field or cycle through the available names.

<command> <name> <message>

Commands:

<none>: send to all
in-game: send to all human players in game.
ico: send to all players in current lobby

/w: whisper
in-game: if player is in game, uses the game chat system (will be recorded), otherwise go through ico.
ico: send directly to player (even if playing a game). tab autocomplete will cycle through all players in channel.

/a: send to all allies
in-game: send to all human allies in game
ico: n/a

/f: send to all ico-friends
in-game: send to all ico-friends, even if they are not in game
ico: send to all friends no matter where they are

/wa: whisper ally
in-game: same as whisper, but tab autocomplete will be constrained to only allies.
ico: n/a

/wf: whisper friend
in-game: same as whisper, but tab autocomplete will be constrained to only ico-friends.
ico: same as whisper, but tab autocomplete will be constrained to only ico-friends.

in-game same as ico

in-game same as ico

-You can now send whispers to players with spaces in their names by using quotes. Autocomplete properly handles these names.

-Rewrite of ico friend status. all clients are now kept up to date on the current status of every friend at all times. This allows for a more friendly ui, the friend list is colored to show who is logged in/playing games. There are globbal events to notify the user of what friends are doing. This can be disabled like the channel notifications.
