crash loading patches for booty shifter

[squinkylabs]

It looks like the json is (now) deserialized before the widget is created. Looks like bad code on my part. There is a widget called PopupMenuParamWidget that attempts to do this better, don't know if that would help.

I inserted a booty shifter.
turned the knobs
quit Rack
ran rack again
boom!

This one can be tested as it is solved. Moved a shared variable to module

[squinkylabs]

yeah, seems fine now.
