- added two new things which can set a sector's color without the need of tags

or scripts. ColorSetter (#9038) sets the sector's color and FadeSetter (#9039)
  sets the fog color.
- added new flags MF5_ALWAYSFAST and MF5_NEVERFAST. These flags unconditionally
  enable or disable fast movement logic, regardless of skill settings.
- added an abstraction layer for skill related settings. This is a preparation
  for implementing custom skill definitions but right now all it does is
  returning the original values but keeping the related information all in one
  place
