* Cleaned up all of the code, checked to make sure that there were no erraneous debug logging.
* To enable debugging, turn it on in the api by changing the following line in item_frames_api.lua:
mcl_itemframes.DEBUG = false -- set to true to see debug output.
* Made the standard Item Frame and the new Glow Frame use the frames API.
Added in backwards compatibility mode.
* Made frames pop out items into the world on the old frames' entities when they are a hidden / broken entity. (Part of the backwards compatibility.)
* Tested locally.
* *Converted the spaces to tabs!*
Should be fully functional and ready for review.
