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.

Omitting all the superfluous tests. Later on we might want a nicer way to specify which apps to test, because they are now hardcoded in runtests.py. (Listdir doesn't do the trick, tried that already :-) )

CSRF validation will only be applied to POST requests, so let's only load .RAW_CONTENT in those cases

Generic permissions added, allowed_methods and anon_allowed_methods now defunct, dispatch now mirrors View.dispatch more nicely

Better error handling for Basic authentication. Catch exceptions that could be thrown due to malformed input
