Add longpress gesture for touch devices
I'm attaching a patch which adds longpress gesture to canvas view and the new experimental flowbox model. It is WIP as it currently has a compile warning (nautilus_files_view_pop_up_selection_context_menu expects an GdkEventButton). But before changing this function i would like to ask for a review if this is the correct approach.
