Update to ZDoom r1799:

- Added PinkSilver's SetActorVelocity code submission (with optimizations.)
- Added the frandom decorate function, which is exactly like random except
  that it works with floating point instead of integers.
- Split the bounce types completely into separate flags and consolidated
  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.
- Fixed: R_CreatePlayerTranslation() only initialized the first truecolor
  palette entry.
- Fixed: D3DPal::Update() used BorderColor == 0 as the condition for skipping
  an entry. It should be SM14 as in UploadPalette().
- Fixed: The aliasing of CPUInfo was still wrong. (Yarr! The things I do
  for you, GCC!) The AMD feature flags weren't stored anywhere, either; not
  that it really matters.
- Add an alternate PIC-compliant __cpuid macro in x86.cpp.
- Fixed: S_LoadSound() did not byte-swap the frequency and length it reads
  from DMX sounds.
- Fixed: PNGTexture must not use the FArchive >> operator as a short hand
  for reading 4-byte integers, because that operator works with little
  endian numbers--a no-op on Intel processors, but bad joojoo on PowerPCs.
- fixed: Weapons must first check if they can be switched and afterwards
  if they can be fired. These checks were reversed.
