Adding project entries required for WinPhone 8.1 to work properly.
Adding utility API functions to remove values from config lists. As an example, this would let you remove a flag in a configuration block like:  removeflags "StaticRuntime"
Adjusting ProjectReference outputs for WinRT / VS projects.
Fixing iteration bug in the remove API method I previously added.
WinRT projects now generate an Appxmanifest file automatically along with the project.
Only generate AppxManifest if none is specified in the project files. Also set the Deploy sln flag on WinPhone apps.
