#1 Filename Cleanup and Dir Structure

[Jason Huebel]

This patch includes addition filename cleanups in the
escape() function:

- Replace "_-" and "-_" with "-"
- Replace "__" with "_"
- Remove trailing underscores

The patch also includes better (IMHO) directory
structure for the rip. MP3's are now ripped using the
./Artist/Album directory structure instead of the
./Artist-Album single-level directory structure. This
provides better compatibility with tools like Album
Cover Grabber and many Web-based MP3 streaming utilities.
