* Fix 'GiveNamedItem' in the game left4dead2.
The method 'CCSPlayer::GiveNamedItem(char const*, int, CBaseEntity*)' does not work in game left4dead2, any given weapon and object immediately falls to the ground, besides, the code is missing a parameter to call this method (even with the added parameter does not give a weapon to hands). Another method 'CTerrorPlayer::GiveNamedItem(char const*, int, bool, CBaseEntity*)' works great, besides it makes it possible to give out all the items that exist in the game.
* Add x64 support
Add x64 support
* Changed argument type to bool.
