Also fix up some return values and stuff to use bool (or void if nothing). I just did it whilst I was here. According to jilles, the return value used to signify whether or not the client had exited. This was error-prone and was fixed a long, long time ago, but the return value was left int for historical reasons. Since the return type is not used (and has no clear use case anyway), it's safe to just get rid of it.

* roleplay commands for charybdis.

|
* adds NPC, NPCA, and SCENE which allow users to send messages from 'fake'
|
|
* nicknames. in the case of NPC and NPCA, the nickname will be underlined
|
|
* to clearly show that it is fake. SCENE is a special case and not underlined.
|
|
* these commands only work on channels set +N
|
|
*
|
|
* also adds oper commands FSAY and FACTION, which are like NPC and NPCA
|
|
* except without the underline.
|
|
*
|
|
* all of these messages have the hostmask npc.fakeuser.invalid, and their ident
|
|
* is the nickname of the user running the commands.
