- Split the bounce types completely into separate flags and consolidated

Browse source 
the various bounce-related flags spread across the different Actor flags
  field into a single BounceFlags field.
- Fixed: P_BounceWall() should calculate the XY velocity using a real
  square root and not P_AproxDistance(), because the latter can cause
  them to speed up or slow down.

- made menu dimming a mapping option but kept the CVARS as user override.
