/*
* 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.
