Version 0.91vdr-0.91

- Fixed displaying colored button texts that are too long.
- Suppressing replay progress display when replaying a DVD.
- Updated channels.conf.cable (thanks to Uwe Scheffler).
- Updated French OSD texts (thanks to Jean-Claude Repetto).
- Improved AC3 decoding when replaying DVDs (thanks to Matjaz Thaler).
- Fixed handling DVB card indexes when using only one card in a multi-card
  system.
- Changed the 'Eject DVD' button text to a simple 'Eject' (the German text
  was too long...).
- Made the font file generation more stable (thanks to Artur Skawina).
- Changed the default value for the "DiSEqC" setup parameter to "off".
- The new command line option '-E' can be used to define where the EPG data
  shall be written to. This is especially useful if VDR runs in a system
  that turns off the video disk when it is not used, and therefore needs
  to write the EPG file to a ramdisk (or turn off writing it alltogether).
  See 'vdr --help' for details.
- Making sure the disk is up and running before starting recording (this
  is important for systems that turn off the video disk when it is not used).
- Added the "Jump" function in replay mode (thanks to Stefan Huelswitt).
  See the description of the "Red" key in MANUAL under "Replay Control" for
  details.
- Fixed displaying editing marks when toggling a mark in "pause" mode.
- If there is no free DVB device to record, the log message will now be given
  only once.
- Made I/O more robust by handling EINTR (thanks to Werner Fink).
