Spring RTS Engine

BATTLEOPENED sends channel as a sentence. In all channel-related commands, it's handled as a word.
Also JOINBATTLE is sending the channel argument, even though it appears undocumented in the protocol.

Transition to JSON?

Please use the issue tracker of the lobby protocol docs in future. https://github.com/spring/LobbyProtocol

BATTLEOPENED sends channel as a sentence.

This doesn't cause any issue/inconsistency, channel names are not permitted to contain whitespaces. The reason is historical.
