Little hotfix with update notice on chat.

• Improved shield overlay material (thanks to Dopey)
  
• Added Elite shield with color, particles and sounds effect
  Each player can choose to use either Spartan or Elite shield
  
• Added health regeneration (off by default)
  Fully customizable with method, delay and regen rate
  
• Added customizable shield color.
  Each player can chose their own color or the default color.
  This feature can be disabled in server options.

• Refractored code
  
• Fixed shield still regenerating if player's armor lowered without directly "hurting" the player
  
• Added a public function to reset the shield regeneration cooldown (haloShld:ResetRechargeTimer(ply))

Fixed error due to recent update (shld_effect/cl_init.lua:55: attempt to compare nil with number)

Fixed depleted arcs not showing anymore.

Shield recharge effect added even if the shield were not fully depleted.

Initial addon creation.
