[vsaddin] What's needed to do to update existing projects to use property pages

[Roest]

There seems to be no mechanism for old projects to upgrade to use the new property page mechanism of the "new" vsaddin. So it's still using the old dialog in the Extensions menu. Is it possible by editing .proj files or something to manually upgrade to that?

If you select the project in solution explorer and go to Extensions -> Qt VS Tools there's an option to convert your project: Convert custom build steps to Qt/MSBuild.
