Create a list of Solid App ideas

[YetAnotherJonWilson]

To give developers an idea of the range of possibilities of Solid Apps, create a list of Solid App ideas and store it in the onboarding pod (aka our backend). Display the list on our site, probably as a set of cards that can be updated: 1) to add possible features, comments, etc., and 2) to add links to repos when developers begin working on them.
