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'
