Improve and extend the archive Web UI (GSoC task)

As you probably know already, The Software Heritage archive can be browsed on the Web. The code powering that interface is a Django application that also implements a Web API.

Several improvements are possible on the archive Web interface and would make great GSoC projects, some ideas to whet your appetite:

• add new source code search criteria and improve the search interface
• add developer-oriented features, e.g., source file history, blame/praise interface, in-browser edit (with patch download), ... (note that this will also require backend design and implementation)
• improve accessibility
• help us design and implement our next API version
