Added A_QuakeEx(intensity x, y, z, duration, damrad, tremrad, sound, flags)

Browse source 
- Unlocks the full potential of using quakes, including the Z axis. Each intensity applies to X/Y/Z planes whenever a player is experiencing it.
- Flags:
- QF_RELATIVE - Adjusts the quaking of the camera to go in the direction its aiming (X: forward/backward. Y: Left/right.)
- Plans for including pitch will be implemented in the future for the Z axis with relativity.
