1.  Default sharing settings

I've created a new settings page to set the default sharing for articles

2.  Article Index

You can now make articles public and show on support page directly from the index

There is also a bulk update (this has always been there)

3. Video embedding

I've added a new component for video embedding so users don't have to create an iframe etc

4. Article rendering

I've updated the css style for the article view to clean up fonts, spacing etc.
