Streamripper configuration

Streamripper is now configurable. Configurable features are setting the output directory for ripped files and enabling automatic importing of new songs to media library. Changes made are pushed to gitorious. I believe this streamripper-extension won't see too big changes anymore, from now on it will be testing and bug-fixing.

The shoutcast UI part however needs to be re-written in my opinion. As it is it cannot be easily extended to support other sources than shoutcast. Also having separate UI for internet-radio and for shoutcast is kinda stupid.

New plan is to refactor the name of the whole thing to something like Stationfetcher and have it appear on Tools-menu. Now it would be easy to just add new sub-menus for other stream sources. I'd like to add support for xiph.com which seems to offer quite nice selection of streams. I estimate this to take a week.
