Half-Life 1 and Counter-Strike 1.6 BETA updated

Changes in this update are:
  • Returned mouse input to using windows messages rather than raw input, this should correct the sensitivity change people have seen
  • Added m_rawinput cvar, if set to 1 this enables using the raw input API's on your OS to get mouse input, usually with lower latency but missing the post processing from your OS
  • Fixed corrupt HTTP downloads if the url sent by the game server resulted in a 404 error
  • Fixed corruption of text input when hitting backspace while composing a message
  • Renamed gl_ztrick cvar to gl_ztrick_old, usage of this cvar is deprecated and caused rendering issues
  • Fixed mouse clicks sometimes being lost
