Version 1.3.1vdr-1.3.1

- Fixed a lockup in the EPG scanner when no non-primary device was available
  (thanks to Martin Holst for reporting this one).
- Fixed a compiler warning about virtual cConfig::Load() functions (thanks to
  Lauri Tischler for reporting this one).
- Fixed a warning about character comparison in libsi/si.c (thanks to Lauri
  Tischler for reporting this one).
- The new parameter "Update channels" in the "Setup/DVB" menu can be used to
  control if and how channels will be automatically updated (see MANUAL).
  This has already been part of the 'autopid' patch by Andreas Schultz and has
  now been adopted.
- Fixed a crash in case there is no DVB hardware present (thanks to Sascha
  Volkenandt for reporting this one).
- Changed calculation of channel ids to make it work for tv stations that use
  the undefined NID value 0 (thanks to Teemu Rantanen for reporting this one).
- Enhanced the SDT filter to handle multi part sections.
- Added support for selecting preferred EPG languages (based upon a patch by
  Teemu Rantanen).
- Fixed a 'const' in libsi/si.h (thanks to Marcel Wiesweg).
- Fixed the 'su' call in 'runvdr' to make it work on systems that require the
  user name to appear before the command option (thanks to Robert Huitl).
- Fixed testing for matching section filters in case they are turned off (thanks
  to Marcel Wiesweg).
- In case of incomplete sections an error message is now logged only every 10
  seconds.
- Fixed a possible NULL pointer access in cEITScanner::Process() (thanks to
  Andreas Kool).
- The actual transponder data is now taken from the NIT and existing channels
  are adjusted if necessary. If the NIT contains new transponders, they are
  scanned for channels during the next EPG scan. Note that only the satellite
  branches are tested, cable and terrestrial need to be tested by somebody who
  actually has such equipment.
