[Suggestion] [1.12.2] Config to allow custom glass to be obtainable in survival

[CplPibald]

Suggestion to allow survival users to be able to craft the glowing travel hut glass, for two reasons. First, it's a cool building block and people are asking for it. Secondly, and more importantly for an admin like me is that it's too easy to grief a hut and too difficult to repair one.

The glass is trivially broken with a single punch, but huts are impossible to repair for most users without summoning an admin out to regenerate the whole hut (which usually results in the new hut appearing on top of the broken one). This is a problem for survival users that want to incorporate a hut into their build. A simple misclick can permanently ruin the aesthetics, to say nothing of griefing or a misplaced creeper explosion.

The first part of this suggestion is to allow the hut glass to exist as an item. Right now not even /give or creative-mode users can get this item, which makes hut repairs impossible even if the admins wanted to cheat the glass in or create a crafttweaker recipe.

The second part is to allow survival users to be able to craft the glass, using a recipe of maybe glass + glowstone dust. Or nether stars and dragon eggs if you want it to be difficult. :D
