Started on rating functionality.

I need to make the rating column work, make sure the conversion works, add it properly to the Shirt object,
and make sure that every window that needs it has it, along with editing the choosing algorithm. I may have done
some of these already, but I dunno.
Made a little more progress
Made a little more progress.
I think it's functionally finished.

I need to test it more, and the stars are way too big, so I need to make them smaller, but
other than that, it's all good. I think.
Moved images to res folder.

I want this to look at least a little professional.
Resized stars.

All I have to do now is redo the choosing algorithm to weight high-starred shirts more.
Finished rating functionality.

I'm going to test the pick algorithm, but I think I'm done.
Dumb mistake.
I made some stupid mistakes, but testing fixed them.
Merge remote-tracking branch 'origin/rating' into rating
Fix the problem with the update window having the same number of stars lit up regardless of how many the shirt had.

I think it's ready to merge, but I think I might sleep on it. Or not.
Remove unnecessary import.
Merge pull request #20 from ddsnowboard/rating
