Version 1.5.1vdr-1.5.1

- Added cDevice::HasCi() so that devices with Common Interface can be avoided
  when tuning to an FTA channel, thus preserving the CAM resources even on budget
  DVB cards (suggested by Petri Helin).
- Fixed i18n characters for the Hungarian texts (thanks to Thomas Günther).
- Now using cPipe instead of popen() in cCommand::Execute() to avoid problems
  with open file handles when starting background commands (thanks to Reinhard
  Nissl).
- Removed 'assert(0)' from cDvbSpuDecoder::setTime() (thanks to Marco Schlüßler).
- Fixed a possible crash when loading an invalid XPM file (thanks to Martin Wache).
- Updated satellite names in 'sources.conf' (thanks to Thilo Wunderlich).
- Adapted 'libsi' to DVB-S2 (thanks to Marco Schlüßler).
- Fixed handling error status in cDvbTuner::GetFrontendStatus() (thanks to
  Reinhard Nissl).
- Shutdown handling has been rewritten (thanks to Udo Richter).
- Plugins can now implement the new function WakeupTime() to request VDR to wake
  up at a particular time (thanks to Udo Richter).
- The HUP signal now forces a restart of VDR (thanks to Udo Richter).
- cThread::EmergencyExit() has been replaced by ShutdownHandler.RequestEmergencyExit().
- Several references to "button" in a remote control context have been changed
  to "key" (based on a report from Marko Mäkelä regarding the "Menu button closes"
  text). The "MenuButtonCloses" parameter in 'setup.conf' has therefore been
  renamed to "MenuKeyCloses", accordingly. This will result in an "unknown config
  parameter: MenuButtonCloses" error message in the log file, so you may want to
  remove that entry from your 'setup.conf' file.
- Simplified the error handling in cDvbTuner::GetFrontendStatus() (based on a
  discussion with Reinhard Nissl).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Increased the maximum number of DVB devices to 8 (thanks to Rolf Ahrenberg).
- The new Setup parameter "Channel entry timeout" can be used to customize the time
  since the last keypress until a numerically entered channel number is considered
  complete, and the channel is switched (suggested by Helmut Auer). Setting this
  parameter to 0 turns off the automatic channel switching, and the user will
  have to confirm the entry by pressing the "Ok" key.
