Files are provided by stdin

All I wanted was a shell command to submit mp3s to last.fm.  scrobbler.pl came closest.

But I found the file/directory/random file thing disagreeable.  I want the shell command to just submit mp3s.  I can select those with echo, find, or find piped into shuf, and then pipe that whole mess into scrobbler.

This version does that.  Pipe one file per line into scrobbler.pl and it'll send each of them to last.fm.  Make sure you use a -t delay - I got missing submissions when I tried scrobbling without that.

Debating adding a check against my user's rss feed to avoid sending dupes.  That might be overengineernig and I'm not all that good with perl.
