gfxToggle

v2.3.0-beta1
- fix: ticket 1; error when /gfxt list - no translation for "Zones: Low"
- fix: potential exposure of 'self' global var
- remove M2Faster, also hidden lod and shadowLOD CVar's
- only RestartGx() if necessary, when special CVar's actually changes
- force RestartGx() when manually loading a set (but only if necessary)
- even if gxRestart disabled, still set the relevant CVar's
- general code tidy-up; remove needless object vars and functions
- rearrange saved vars structure (all sets will be lost)
