(overlay): consider adding MdPopup similar to MdDialog

[mmalerba]

Many components (select, autocomplete, menu, datepicker) have similar boilerplate related to opening a popup attached to some trigger element. It would be nice to add something like MdPopup that would make it easier to do this (like how MdDialog does for dialogs).

This would be very nice. And I think possibility of other trigger methods should be considered as well.
