All top level modules are included. Ready for diving into the modules and documenting/ enhancing already existing docs.

Getting rid of all errors and warnings that show up when building the docs, to make a clean start with the library documentation .

rename : docs/library/authenticators.rst => docs/library/authentication.rst
rename : docs/library/emitters.rst => docs/library/renderers.rst

Stole some code from djangorestframework/runtests/runcoverage.py so that coverage is also implemented for the examples. Because Jenkins looks for a coverage.xml file for all defeined projects in tox.ini we need it to pass the tests.

The test was bad. It expected 11 snippets while the view made sure (as designed) that there would not be more than 10 snippets stored on disk.
