Custom Action - Variable: MultiBoolCheck

This is a Custom Action that is used to check a unlimited number of global boolean variables if they meet given conditions. I use it to clean up my ActionLists if there are to many variable state checks in a row.

To describe it as simple as possible:

It can turn this

into this:

Important to know:

- It only works with global boolean variables

- It does not support ActionList parameters

It is based on the "Variable: Check" Action. Here's the code:
