Replace "Authors" with "Partner Projects" rotating carousel

[wlpotter]

We would like to replace the "Authors" card with a rotating carousel featuring the various Partner Projects of Syriaca.

These will include:

• John of Ephesus
• SPEAR?
• SMBL?
• Others?

Each will need a background image, short description, and link to project

All will have a link to "view all partner projects" that goes to an anchor on the projects.html page (to be created)

• the top and bottom of these cards will also link to this same projects page

This should be a rotating carousel, where the images change every 3ish seconds, fading into the next
