Version 1.3.10

- Fixed some default parameters in 'skincurses'.
- Fixed cBitmap::DrawPixel(), which messed with other bitmaps' palettes in case
  the pixel coordinates were outside this bitmap (thanks to Sascha Volkenandt for
  reporting this one).
- The cBitmap::DrawText() function now doesn't set any background pixels if the
  given background color is clrTransparent. This allows drawing "transparent"
  texts (suggested by Sascha Volkenandt).
- The cBitmap::SetXpm() function now ignores unused "none" color entries, which
  some broken graphics tools write into XPM files (suggested by Sascha Volkenandt).
- No longer setting lnb voltage if the frontend is not DVB-S (thanks to Marco
  Schlüßler).
- Fixed displaying the current channel when switching via the SVDRP command CHAN
  (thanks to Jürgen Schmitz for reporting this one).
- Fixed missing audio after replaying a DVD (thanks to Marco Schlüßler).
- Added a note about the default assignment of the color keys to MANUAL.
- Added a note about NPTL ("Native Posix Thread Library") to the INSTALL file
  (apparently the "fix" in version 1.3.0 didn't really fix this).
- Modified 'libsi' to require callers to state the buffer sizes when getting
  strings in order to avoid buffer overflows (thanks to Philip Lawatsch for
  debugging a buffer overflow in eit.c).
