SA-MP 0.3d RC4 Client and Server Update

Here comes the latest SA-MP 0.3d RC4 - this is the fourth release candidate + I added a server for Linux systems so that everything would be included.

So here is the current list of changes:

• Slots for players on the server have been increased (up to 500 slots).
• MoveObject will not interfere with rotation unless rotation parameters are used. It won't interfere with SetObjectRot() either.
• Resolved 2-sided fence texture issue in area 51.
