Version 0.90vdr-0.90

- Modified the display of the channel group separators (thanks to Markus Lang
  for this suggestion).
- Added support for replaying DVDs (thanks to Andreas Schultz). See INSTALL for
  instructions on how to compile VDR with DVD support.
- Fixed replay progress display in case replay is paused while watching an
  ongoing recording.
- Ringbuffer uses semaphores to signal empty/full conditions.
- Fixed calculating the timeout value in cFile::FileReady() (thanks to
  Wolfgang Henselmann-Weiss).
