Add black hole main menu scene and REM FREELANCER logo

Freelancer.exe and rp8.dll built from REM-Client 0adfd18; the other client
modules are unchanged from the 1b46830a build.

- Intro5_Base: a fourth main menu scene with a supermassive black hole
  traced by the renderer, Omega-41's starsphere lensed around it, a rock
  planet and a Liberty battleship, cruiser and five Defenders crossing.
  Its place and look are set in DATA/INTERFACE/intro_blackhole.ini.
- The main menu logo now reads REM FREELANCER, built from the original
  glyphs, in every resolution variant except the vanilla one.
