Track phases in combat

[Jonathan Lange]

OK. It's really, really important that the bot track who's turn it is, and what segment it is. Otherwise I'll die.

Also need ways to kill people off from combat and to introduce new foes in the middle of combat.

This depends on set being implemented.

[Jonathan Lange (jml)]

A couple of things:
* It needs to be really, really obvious that a person must now act
* Ideally, Joybot will a) alert the current user and b) warn the player who's turn it is next.

For example.

<GM> !next
<joybot> *** SEG 4, John of Bantor (Feranir up next) ***

OK, this is fixed, except it apparently didn't need set to be implemented.
