Implement CBaseEntity::Fire<Bullets[3]|Buckshots> hooks. (#202)

Browse Source 
* Implement "CBaseEntity::Fire<Bullets[3]|Buckshots>" hooks.
* Added new hook table "GamedllFunc_CBaseEntity".
* Added new hookchain argument type "ATYPE_VECTOR"
* Added ATYPE_VECTOR case in Get|Set<HookChainReturn> natives
* Added ATYPE_VECTOR in SetHookChainArg native
