The previous approach had the problem of losing any action internal
state changes in the created copy.
Revert "Fix temp var values of actions not being accessible"
This reverts commit df42538319.
Revert "Don't block UI while running actions"
This reverts commit a01d26e25d.
This should avoid crashes when actions or conditions are performed in
parallel to the main macro loop and will improve the UI responsiveness
in some scenarios
* Script can be defined in the macro segment or loaded from a file
* Supports both LUA and Python
* Can be used for actions and conditions
* obs_script_create and obs_script_destroy are resolved at runtime
(Let's hope the API remains stable)
