Detect changes in environment variables

Process environment is build up in the following order:

• Machine

• User

• Parent process variables (explorer, cmd etc)

Liquit Filter check order for env var exists and value:

• Check Process env

• Check User env

• Check Machine env

Liquit start process:

• Clone current Process env

Issues:

• Filters look at captured env vars, if a value is changed (outside of Liquit), Liquit doesn't detect it.

• Process start clone captured env vars, changes outside of Liquit are ignored

Posible fix filters:

• Check process last

• Sub issue, if a variable is deleted, process still contains it (make a existing variable list at startup to detect deleted variables?)

Posible fix start process:

• Project user and machine variables over process variables

• Remove detected deleted env variables from above result
