Add chat token support for say cmds.

Perhaps something more like:
$h - health
$a - armor
$f - force pool
$g - ammo in current weapon
$n - name
$s - force side
$l (L not I) - location
$d - last death location
$c - team color (red,blue,free,spectator)
$t - team name (^1Red Team, ^4Blue Team, ^3Free, Spectator)
$e - enemy team color(blue,red,free,spectator)
$w - current weapon name
$i - player id
$h - siege class name
$o - current held flag in ctf

Open for other styles, we used this method in ETF, even allowed $r to show reader name. I used a different method in EnsiMod though. More along the lines of:
[h] [a] [f] [g] [n] [s] [l] [d] [c] [t] [e] [w] [id] [cl] [o]
