Group list:colors and format

This script changes the format and color of the list you see when you type "group". See the comments in the script for more information.

;Bug reports, suggestions and/or diffs are appreciated, '''sulfar''' _AT_ ''inbox'' +DOT+ ''com''

;Colors
;  hp and mana are yellow if they're <= 50%, red if they're <= 20%.
;  tnl is yellow if it's <= 250, red if it it's <= 100.

;The original group list has this green, cyan, etc pattern.  With no default
;  color set it'll keep as much from that pattern as it can, which is nice by
;  itself, but might be confusing if the group is hurt and you get red, cyan,
;  green, yellow, green, cyan.  Setting a default would change that to red,
;  <default>, <default>, yellow, <default>, <default>.
;So if gls_default_color is an empty string it will keep the colors it got from
;  avatar.  If it's set to a value that value will be used as default color.
;
;/set gls_default_color=
/set gls_default_color=cyan

;I also made the columns align differently, so the hp/hp_max and mana/mana_max
;  aren't just left-aligned, but the '/' is at a fixed position.  I like that
;  much better.

;Original:

; 2|973 Hero Enchantress  Stand 1765/1765   6039/6110   4114/5216   819    1000
; 3|  6 Lord Kimla        Stand 2086/2086   1095/4686   4283/4283   14458  1000
;
;With this substitute:
; 1| 24 Mag  Darkfader    Stand   213/213     538/538     268/268   1296   1000.
; 2|973 Hero Enchantress  Stand  1765/1765   6037/6110   4114/5216  819    1000.
; 3|  6 Lord Kimla        Stand  2086/2086   1020/4686   4283/4283  14458  1000.

;It appends a dot to each line so you can easily see the trigger is working.
