Remove rang and use fmtlib for printing coloured messages.

This supports more platforms (e.g. Haiku) and is actually still
maintained unlike the former.

All of this code should really be cleaned up for release (maybe by
adding something like Anope's LOG_CONSOLE) but for now I've just
replaced it with the fmtlib equivalent.
