#37 implement ignore/filter specific filetype in browser view

[skizzo]

and here is no. 3 =)
...may be handy to not show backups, archives or lyric files in the song folder.
gain would be sorting and better finding of useless/unused files.

some option to filter or ignore comma-separated file types on folder load would rock!

my media manager/player automatically grabs lyric files and saves them to the audio files' folder. so nearly every ultrastar song got the unused file flag, which makes it hard to track useless files.
hope that helps,greets =)
