The Last War-Birds v. 1.5

This update fixes bugs, updates some photo locations, re-adds some music that had not been working properly, and adds the credits.txt file.  It's now essentially as I wanted/expected it to be after a 2 week game jam.  I may still continue to update things like the player choices and perhaps attempt to adjust the color a little to make it more consistent, but for now it's in a state where it is what I put together for the jam in its "best" form.  Thanks for trying it out!
