amxx reapi Advanced Slot Reservation 2.2.0

• Implemented a new reservation method:
  • Checking for a password field in player's userinfo. Thanks BlackSignature and WaLkMaN for the idea.
    
• Implemented more methods for the kicking player algorithm:
  • Kick only from spectators. If there is no spectator, then go to the next search method.
    
  • Kick player by played time ( the oldest player on the server or the newest player on the server ).
    
• Added admin immunity flag in configuration file ( which flag should be skipped from algorithm ).
• Added kick message field in configuration file.

• Added reservation type either by IP address or name.
• Added some settings for connected players checking.
• Added parsing player's name in SV_ConnectClient hook ( Thanks HamletEagle for showing me this way ).
• Improved connected players checking code.
• Thanks for WaLkZa for a small fix
