Version 1.5.9vdr-1.5.9

- Fixed handling locale directories with a large number of entries (thanks to
  Anssi Hannula).
- Updated Turkish language texts (thanks to Oktay Yolgeçen).
- Fixed stripping the context in I18nTranslate() (reported by Christian
  Wieninger).
- Fixed detecting whether a particular locale is actually supported.
- Added a note about LANG having to be set to a valid locale in INSTALL
  (suggested by Matthias Fechner).
- Fixed some compiler warnings with gcc-4.2.0 (thanks to Matthias Schwarzott).
- Fixed setting the locale file name in i18n-to-gettext.pl (thanks to Matthias
  Schwarzott).
- Changed the default for LOCDIR in Makefile and Make.config.template to
  "./locale", so that internationalization works by default when running VDR
  from within its source directory (suggested by Anssi Hannula).
- Added the new i18n macro trVDR(), which can be used by plugins to mark
  texts they want to reuse from VDR's core translations (suggested by Matthias
  Becker).
- VDR now uses the default configuration directory as defined in the CONFDIR
  varable in the Makefile (thanks to Thomas Schmidt).
- The SVDRP command LSTC can now list the channels with group separators if the
  option ':groups' is given (thanks to Andreas Mair).
- Added a missing error report to cCuttingThread::Action() (thanks to Udo
  Richter).
- There can now be more than one OSD at the same time. At any given time,
  however, only one of them can be active (and thus visible). This is to
  allow displaying things like subtitles in an easy way. A cOsd therefore
  now has a "Level", and only the OSD with the smallest level will be
  displayed. The level 0 OSD is special, and there can only be one with
  this level. If there is more than one OSD with a particular level, only
  the one that was created first will be displayed.
  Plugins that provide an OSD need to adjust their cOsdProvider::CreateOsd()
  function to hand through the Level.
- Fixed checking for ttDolbyLast in cDevice::SetCurrentAudioTrack() (thanks
  to Marco Schlüßler).
