Removed redundant code from FPS controls.

The functionality removed is repeated directly after this code block.
The entire process is actually being done twice, which is undoubtedly incorrect or otherwise very unclear.

Given that it is simply doing 3 actions:

a) Adjusting the pitch/yaw based on the mouse position deltas, then multiplying that by the lookSpeed.
b) Clamping, transforming the pitch space (to the X,Z coordinate frame) and then converting the pitch/yaw (lat/lon) to radians.
c) Calculating the target position 100 units in the direction specified by the pitch/yaw.

This process has no reason to be repeated.
Deleted unnecessary branch indenting.

This is a formatting commit, it removes an unnecessary else branch.
