Converting some of the rst documentation to markdown.  Attempted to
preserve whitespace and line breaks to minimize cosmetic change.

Lots of updates to the README/INSTALL.md.

Fixes #4601.

Factor out the reverse proxy info to a separate file, add some more info on
reverse-proxying the federation port.

The readme was getting pretty unmanageable and hard to grok. This is an attempt to simplify things by moving installation instructions from the README to a separate file. I've tried to resist the temptation to fix too much stuff while I'm here - it mostly just copies-and-pastes from one doc to the other, and changes from rst to md syntax.

Make the dependencies more like a standard Python project and hook up the optional dependencies to setuptools (#4298)

This is based on the work done by @krombel in #2601.

And mention of Vector as a client replaced with Riot.
