Version 1.5.13vdr-1.5.13

- Fixed the declaration of cSubtitleObject::Decode8BppCodeString() (thanks to
  Gregoire Favre).
- The new setup option "Miscellaneous/Emergency exit" can be used to turn off
  the automatic restart of VDR in case a recording fails for some reason.
- The kInfo key is now propagated to any open menu, so that it can react to it
  in a context sensitive manner (suggested by Andreas Brugger). If there is
  no menu open it will show the info of the current broadcast or replay.
- cTimeMs now uses the monotonic clock, if available (thanks to Petri Hintukainen).
- Fixed cVector::Clear() and cStringList::Clear().
- Added cString::Truncate().
- Fixed the "i18n:" target in the "newplugin" script, so that it can create the
  initial *.pot file.
- Fixed handling the '-l' option.
- Fixed error handling in cCuttingThread::Action() (thanks to Udo Richter).
- Fixed a loss of the date display in the "classic" skin's main menu (reported by
  Andreas Brugger).
- Added a missing setting of lastFreeMB in cMenuMain::Update() (reported by
  Andreas Brugger).
- Added '-Wno-parentheses' to the compiler options in order to avoid silly compiler
  warnings for expressions like 'a || b && c', where GCC 4.3 wants to force the
  programmer to write 'a || (b && c)', while everybody knows that '&&' links
  stronger than '||' (reported by Tobias Grimm).
- Updated the Hungarian language texts (thanks to István Füley).
- Fixed displaying weekday names in the Schedule menu if the system uses UTF-8
  (reported by Jiri Dobry).
- The new plugin "pictures" implements a simple picture viewer.
  See PLUGINS/src/pictures/README for details.
- The automatic shutdown is now suppressed if the remote control is currently
  disabled (suggested by Helmut Auer, implemented by Udo Richter).
- Added a section about "Logging" to PLUGINS.html (suggested by Torsten Kunkel).
- Enhanced the SVDRP command CLRE to allow clearing the EPG data of a particular
  channel (thanks to Benjamin Hess).
