Better sprite sheets and Trinket is working again

Just a quick update. The browser version of this game is once again working on Trinket.io -- they were having issues on their end, and eventually were able to correct them. Amulet has had issues on Trinket because, I guess, too many sprite sheets, so I consolidated the sprites into one sheet and everything seems to be happier with them.

So, if you'd like to try this in somewhat lower rez in the browser, You Are the Amulet on Trinket.io should be working again.

The new downloads just contain this new sprite sheet. I deleted some unused files as well. All of this is also up on Github. 

Thanks again!
