Thanks. I pushed this with some changes. Perhaps more changes than 
appropriate but I hope I made more improvements than errors.

One major comment, though:

I think we should make it clear that there are two independent options:

Kallithea can be
* run from source (repo or tar with setup.py develop) or
* installed from source (repo or tar with setup.py install) or
* installed from pypi

Package installation (primarily with pip from pypi, alternatively with 
"setup.py install") can be
* in a virtualenv or
* global (or ~/.local).

(The option of pip or easy_install or whatever is ignored.)
