* librb is no longer a separately configured subproject.
* charybdis is now a standalone directory with a binary.
* Include path layout now requires a directory ircd/ rb/ etc.
There are two important caveats here, however:
1) Aliased commands have more than 8 parameters will be truncated;
there's nothing I can do about this.
2) Parameters with colons will not be handled as you expect. Again,
nothing I can do about this.
