(thanks to Mehdi Karamnejad for reporting a problem with garbled UTF-8 EPG data
and helping to debug it).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- When checking whether a video directory is empty, file names that start with a
dot ('.') are now ignored and will be implicitly removed if the directory contains
no other files. This fixes the leftover ".sort" files that were introduced in
version 1.7.29.
