plugin text commands: handles coroutines + better command parsing: - async coroutine can now be used for text commands (in addition to Deferred and regular callbacks) - isidentifier is now used to detect a command, allowing to use "_" in command names - if message starts with a single `/`, it is never sent (previously it could be sent is some corner cases) - don't use OrderedDict anymore as dict now keep insertion order by default

You'll find install instructions in documentation (see doc/installation.rst).
