Multiple fixes for mirrors. (#1192)

* #1064 Fix for mirror surfaces going black when the roughness is set too high.

* #1130 Fix for the user's avatar not appearing in mouselook in a mirror.

* #1059 Disable mirrors on low settings per the feature table.

* #860 Modify the settings UI to better reflect that we only have two AA modes: off and FXAA.

* #1191 Add some settings for mirrors in preferences.

* #1185 Add support for runtime mirror resolution changing.  Useful for quality settings, and auto-FPS.
