Consistent sections order & headers in contrib docs
Summarize contrib apps on docs index
- Remove contrib app overview
- Decided against using an English name for the apps, as they are not standardized
  and the description seems like enough.
Standardize contrib app installation docs
Syntax highlighting for all code snippets in contrib docs
Update nav bar info in httptester docs
Merge pull request #310 from rapidsms/feature/310-django15

Add Django 1.5 to Travis and Tox
Better docs for BaseHandler.test
This was mentioned in #265 and #220 but those issues were closed before the change was made.
Changes in response to comments from @dpoirier
1. Autonumbering was not working probably because of extra paragraphs in list
2. Messaging should be numbered to be like httptester and locations

Refs #312: Build docs cleanly

* Fix all the warnings, even in nitpick mode:

** Give each reference a unique name
** Add intersphinx config so we can link to Django settings
** Add blank lines in nested list (RsT insists on them)
** Remove some links whose targets no longer exist

* Change Makefile and tox.ini to always build docs in nitpick mode
  and treat warnings as fatal
* Change .travis.yml to use tox to run tests, but in a way that still
  lets Travis distribute the work across multiple systems if it wants
