Proposal: Richer project descriptions

Just going to toss out an idea myself and others have been kicking around for a few years that I'd really like to see implemented.

It would be nice to take advantage of the fact we require descriptions of projects for submission to eboard for PR/record keeping purposes. Concretely, I'd like the following functionality (and happy to implement myself):
- [ ] project descriptions may include some form of richer text, preferably markdown or something similar, possibly user choice.
- [ ] Images and other attachments (but hopefully not malicious code) may be attached.
- [ ] Projects must be marked as published in some fashion. Ideally anything that is a major project should be worth bragging about.
- [ ] Public facing project blog should be exposed, attributing contributions to project authors, this should either be linked to by the main site or incorporated.
