Updating Apache instructions.

I've spent days of trying and searching through google with all sorts of conflicting results. None of which ended up working for getting mod_proxy_uwsgi working. The best I could get was the base URL working but any other routes would not. I tried using "uwsgi://", I tried using "uwsgi://appname/", I tried using "uwsgi://localhost/". I tried using stacking ("uwsgi unix:/path/to/socket").

This is all on Ubuntu 16.04. (uwsgi 2.0.12 and apache2 2.4.18).

Removed recommendation for mod_proxy_uwsgi over mod_uwsgi, and included a complete example of mod_uwsgi usage.

@linsomniac please try newer releases, 2.0.13 have mod_proxy related fixes.

Ubuntu 16.10 has a Apache 2.4.18, which does seem to work properly using the paths in the example. Leaving references to the error, adding notes about 16.04 version of Ubuntu and 2.4.13.
