-Added: Fadeout when skipping track
-Added: Option to set initial brightness check (on with warning/on without warning/off)
-Added: Volume boost value is saved in the settings file and restored at startup

-Added: ATRAC3 playback (*.aa3, *.omg, *.oma) via Media Engine (plays fine with CPU @ 20Mhz) (many thanks to joek2100)

-Added: Automatic cpu clock based on filetype.
-Fixed: Directories are now listed before files.

Some notes:
-Playing MP3 via Media Engine Volume Boost and FFWD/REW doesen't work
-Playing ATRAC3 Volume Boost doesen't work
-Initial clock frequencies are higher than needed (to avoid problem if you have some active prx that inteferes with the app), try to lower them.
-Adjust your options.
