Streamline installation doc, now using pip (#252)

* Fix conf files to reflect module renaming

Python module was renamed budget → ihatemoney (see #243 and 6923367).
Now, "budget" relates to nothing.

* Harmonize `APPLICATION_ROOT` doc with other settings

* Fix link markup

* Switch documentation to recomend pip over git

- Update installation instruction
- Clearly separate dev setup from installation
- Some rewordings/section-ization by the way

* Add a hint on how to find the static path

This is a downside on the pip choice over git for installation.

We will have to ease that a bit. By doc or by code, before next release.

* Make the nginx deployment doc more accurate

* Add a big fat warning about SECRET_KEY in doc
