Increase client performance

Increase performance by 'caching' settings where safe to do so.

Performance of main client loop up to 2x faster
In places, up to 3 times faster

NOTE 1: This does not mean a 2x increase in framerate. Increase in fps may be up to 1-2fps
NOTE 2: This local 'caching' of settings is not optimal and an alternative solution will be worked on after 0.4.11 is released
