Enchancement Unbound

Enchancement Unbound 1.0.1+1.20-20

• Removed Curtain (the hoe enchantment) and added its rendering features to veil (see the config option Veil Users Separated From World). If I feel like it (and enough people request it), I'll revert the changes.
• Only players can now be rendered with the end portal shader (due to the removal of the Curtain enchantment. I welcome other modders to play around with the RenderLayer and see what they can do with it).
• (Hotfix) Fixed Ascension typos and incorrect functionality
• Updated README accordingly. (This is implied. Will probably be always done, but omitted from the changelog from now on unless I feel like it.)
