Implemented a screen shake effect system in the viewport class.

The screen can either be "nudged" in a random direction with a specific
intensity or you can define an exact x and y intensity, decay factor and
duration. On a tmwAthena server an effect is triggered when the player
character dies. A method for stopping all shake effects is also
implemented, but not used yet. I added a netcode message for Manaserv to
trigger an effect server-sided. Because our protocol has currently no way
to transport floating point values, the decay is transported as a fixed
point value with 4 decimals which is entirely sufficient for this purpose.
