- ChanSort didn't work properly for Turkish (and other system locales) that don't translate ".bin" to uppercase

".BIN" and ".BIN" to lowercase ".bin".
- Philips: Removing a channel from a list is no longer possible (because it is not supported by the TV's import).
  When saving a file, all unsorted channels will be placed at the end of the list.
- support for Philips Repair\mgr_chan_s_fta.db lists is now read-only. Files can be used as a reference list,
  but modifying them won't be possible.
