first draft technical board/code of conduct
Fixed PageField to work with Django 1.7

When migrations call ForeignKey.deconstruct, it manipulates the `to` argument in kwargs.
Changed this to use `to` in kwargs instead of hard coding so migrations work.
`limit_choices_to` is not a valid kwarg for forms.MultiValueField

Added branch policy documentation
First approach at a proper overview in the docs

Added a stub for editing basics doc that is focused on non-technical audiences.
Added to the 'how to contribute' to explain how to set up local environment for testing documentation changes.
A wholesale restructuring of the documentation.

The existing content (some of which will have to be reworked to fit better) is
now in the following main sections:

* Getting started (introduction): step-by-step tutorials and guides to
  get you up and running
* How-to guides (how_to): guides covering more advanced development
* Key topics (topics): explanations of key parts of the system
* Reference (reference): technical reference for APIs, key models and
  so on
* Development & community (contributing)
* Using django CMS (user): guides for using rather than setting up or
  developing for the CMS
* Release notes & upgrade information (upgrade)
