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.
The "core" macro conditions and actions have been extracted out to the
"base" plugin.
The library now mostly contains functionality which is required across
all plugins and (e.g. definitions for macro segments).
The goal is to reduce the complexity and cross-dependencies and group
the source files in a better way.
This should relsove the "library limit of 65535 objects exceeded" build
issue occuring in some Windows build environments.
