Bring across global variables in debug mode

[bnewey]

Currently when debug mode is entered in analytic apps and macros, the direct inputs to the app/macro when the error occurred are hardcoded into a workflow in debug mode, so that errors can be more easily detected.

However, inputs into analytic apps also create global variables which can be used in the more code-heavy aspects of Alteryx such as the Formula Tool. These are not updated in the same way which can cause workflows to break in debug mode - it would be really helpful if global variables could be updated in the same way as the inputs into tools are.
