Damage displayer by Lulu the hero(M_Lajos@hotmail.com)
 
A more detailed damage displayer then advanced bullet damage(abd)
 
Colors are being displayed around the cursor accordingly:
  yellow  - friendly fire
  red     - damage taken
  blue    - inflicted harm
  green   - self harm
  white   - objects( eg. bomb explosion or fire )
 
Version history:
  1.4  - fixed team indication in cstrike
  1.3  - removed team coloring to make plugin applyable to mods other then cs
         turned back to switches to increase sourcecode's readability
  1.22 - removed some variables to reduce resource usage
  1.21 - added team specific colors( T = red, CT = blue, OTHER = magenta ) in both harm and damage
  1.2  - turned switches into ?: statements and clearing out a few variables this way
  1.11 - more optimalization and extracting datas, restructuring if cases, turning them to switches
  1.1  - optimazed code, added friendly fire coloring in damage, plus damage HARM non players
  1.0  - started project: indicating friendly fire(yellow), normal fire(blue) and damage(red)
 
Future developements:
  - Indicating damage done on/recieve from objects, such as breakable things or monstermod monsters.
