Borosilicate windows

- This is the second part of my PR that added phoron windows to protect the SM core from fires
- Borosilicate windows are heat resistant  versions of regular glass windows. This PR renames them (from phoron windows/phoron glass/etc.) and adjusts the fire resistances
- They are no longer completely fireproof. Instead, all window types have fire resistance variables - maximal safe temperature and amount of damage taken if temperature exceeds this limit.
- Regular: 100C, Regular Reinforced: 750C, Borosilicate: 2000C, Borosilicate Reinforced: 4000C.
- Adds alloying recipe to make borosilicate glass. 2 sand + 1 platinum alloy.
