Formatting needs to be implemented as an argument to the clone() method

[shyguyNC]

Right now, Mp3manager.clone(source, dest) always copies and renames in the same format '[artist] - [title].mp3'. This is, of course, very limited, and the main weakness of the gem holding up its release imo. We need to come up with a good format. I propose the following: a simple string, with tags to be inserted as [tagname]. This will be passed in as an argument to the command line version, or to clone(), if called from another ruby file.

example: [artist] - [album] - [title] would clone the mp3s along the lines of 'Zamfir - Pan Flute Crazy - Pan Do Attitude (Extended Cut).mp3'

this formatting should not allow any characters that aren't valid parts of a filename. Also the '/' character should be reserved to indicate that new directories should be created (we'll track that functionality in another issue). Other things to figure out:

• what do we do when the specified tag is blank (empty string) or doesn't exist?
• what do we do about duplicate files?

any other ideas welcome here, this issue is also for brainstorming. :)

I committed some code that implements this feature last night. but it still needs some tweaking, specifically:

• Handling non-existent/empty tags
• Duplicate files
• Unit testing (Issue #1, my favorite!)

Not ready to call this done yet .. needs some unit tests
