API: CSPlayerWeapon integration + new members and functions (#850)

- Member name changed to m_iStateSecondaryAttack
- Member type changed to uint8_t which has same size of bool but allows more values than true or false (this wont break API compatibility)
- Moved logic inside HasSecondaryAttack to correctly alter function return based on m_iStateSecondaryAttack, which can be (0) no value / null (1) set (2) block
-Removed logic in CBasePlayerWeapon::Spawn that caches the return value of HasSecondaryAttack, as this can only be overridden when set, rather than always
* Improve API compatibility
