Make deployed Qt Quick imports code signable

The OS X code signing process enforces strict code/data
separation. Split up the Qt Quick imports; deploy
.dylibs to "Contents/Plugins/quick/", deploy .qml files
and other resources to "Resources/". Create symlinks
to the dylibs so that Qt Quick can load the imports
as usual.
