Make Deck JS a Vendor Module

Earlier versions hacked on the SCSS from Deck directly, leading to
potential maintenance conflicts and some annoying CSS cascades.  Instead,
we should use Deck as an as-is vendor library and apply changes to our own
scripts/styles to account for issues rather than hacking directly.  Using
a vendor library also helps keep our work on the plugin itself.
Move CKEditor to the vendor directory
Move mediaelement code to the vendor directory as well
