Update wxGlade importing to better support python-settings
Description:
While wxGlade only support a small subset of the wxWidgets controls that wxFormBuilder supports, it does have significantly better support for Python code. We need to take a pass through our wxGlade importer and add more support for the Python-specific settings that wxGlade uses.
It's worth noting that there aren't a lot of wxGlade projects on github -- I found only 5 pages of *.wxg files. I've downloaded several dozen of the most current ones to provide testing. Between the low number of projects, and the limited support for wxWidgets in wxGlade itself, working on the Importing is a somewhat low priority unless someone specifically requests a better conversion.
That said, I did just submit a PR to update importing, and I plan on doing one more PR once I've added some additional debugging/testing functionality to wxUiEditor.
This still needs more work, but it's not worth holding up the 1.2 release for, so removing the milestone.
