Merge branch 'oembed_branch' into 'nightly'

Browse Source 
purify oembed html and don't allow cdata

hopefully we never need stuff in cdata

reason for this is that this link serves javascript in its oembed data: https://www.maketecheasier.com/switch-windows-10-to-linux/

see:
https://www.maketecheasier.com/wp-json/oembed/1.0/embed?url=https%3A%2F%2Fwww.maketecheasier.com%2Fswitch-windows-10-to-linux%2F

i don't feel we want that in our database.
