Merge a24bca32580f88bc63a1ff15dfacc86673f03a59 into c969f5ed155c93c55bdbc5a43c17d4876c0ac6eb

this removes the old "virtual global table" which allows
getting environment variables via just their names in lua.

this means:
an environment variable (like TERM) would need to be accessed
via the `env` table instead of just using TERM in lua.

`TERM` -> `env.TERM`
they can also be set via `env.VARIABLE = 'value'
