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.

未指定文件、测试或入口点。首先定位现有的项目提交和描述流程，然后确定富文本、附件、发布状态和项目博客将如何结合。完成的标准是制定出一份已确定且范围明确的实现计划，涵盖这些要求及其安全影响。
