sin-ack b30b7de2d2 ModelGallery: Add the new Model Gallery application :^)
This is an application analogous to WidgetGallery, in that it tests
various capabilities of LibGUI models. Right now it is pretty bare, but
as more work towards LibGUI models is done regarding persistent model
indices, more demos will be added.
