Cleaned MobMonolith

Cleaned up the code in MobMonolith a little. Removed some unused
variables shuffled functions around.
Minor Changes

Fixed up indentation in RenderMobObelisk and MobMonolith automatically.
Changed Monolith Jitter

Changed Monolith jittering to use trigonometric functions for a smoother
rate of change, and also made the speed and movement easily adjustable.
Made very minor changes to MobMonolith code - just reorganizing.
