True remove patch (shift+d removes file from filesystem)

Hey!

I have found this player not long ago and it is wonderful! The only big thing it lacks is the lack of "remove_from_filesystem" command. Because I download a lot of unsorted music and while listening I want to delete files I dont like (not to waste disk space).

So, I've made a small patch:

http://polosataja-patches.googlecode.com/svn/trunk/moc/moc_2.4.0_true_remove.diff

that adds "D" (shift+d) command that deletes a file (or a directory if it is pressed in the left pannel).

P.S. I'm new to C development, so I want to know, how is it ideologically correct to implement this command? Fork()ing linux standart "rm" command or writing everything yourself using unlink() and rmdir().
