Pre-Q/A Review Ready

@ByronDarlison @dlugo00 @mmeiers Development is complete for this widget and is ready to be reviewed prior to Q/A. I've set up a couple test presentations for quick access in the test RVA platform under Rise Vision Test Co.:

*Responsive Test Presentation*
Name: Web Page Widget Test (Responsive Presentation)
http://viewer-test.appspot.com/Viewer.html?type=presentation&id=2bc48027-46b3-40bc-8e7b-c81f9dbd89a6&showui=false

*Fixed Test Presentation*
Name: Web Page Widget Test (Fixed Presentation)
http://viewer-test.appspot.com/Viewer.html?type=presentation&id=3154c07f-fe5c-4eb7-8161-be32e3281eb9&showui=false

I have also updated the Release Notes google doc for this widget which is now called Web Page Widget Release Notes.gdoc. I'm not sure if I should be attaching that document to the Trello card, or providing a link here, or sharing the document with particular people. Just let me know.
