Pruning of unnecessary assets

Some assets leftover in the demo were unnecessary for it, so they have been pruned to reduce the size of the download. Nothing has actually been updated otherwise, there is no need to redownload it or anything!

If you do download it again, find your save folder which is located in your user/appdata/local folder and rename the one called "Birth_ME_Code" to "Birth_ME_Code_Demo" in order to keep your saves intact.
