💥 Change set-popup-rule! usage

Now accepts a flat plist of all its former parameters, including new
:parameters and :actions properties to increase your control over the
fate of your windows.

The old usage of set-popup-rule! is deprecated and may not work right!

The :ui popup module has also seen a major refactor to improve
efficiency and load times.

Sorry! This is the last "big" change before 2.1!
