[Safe WIP] Presets: PCSX2 configuration for dummies:

- When Presets are disabled: Nothing changes compared to earlier pcsx2 versions.
- When enabled: All important config options are grayed out, and a slider is used to select 1 of 6 overall config presets, 
  in the range of safest (and slowest) emulation, through trying to balance compatibility and speed, to way-too-many-hacks.
- TODO: 1. Resolve UI inconcistencies ("Cancel" button). 2. Fine-tune the presets. 3. Slight refactoring.
