The test_views.py file was getting too large, with all the views it

was testing. Most of these were intermixed in one big class, almost all

with outdated function names and some placed wrong.
This splits out the file into a series of per-view files. The tests

haven't changed (and many of them are definitely still very outdated),

with a few exceptions:

The test names have changed to remove any view namespacing (leaving

   that to the class)
The docstrings specify the new class names.
Calls to self._get_context_var(response, varname) are replaced with

response.context[varname].

All unit tests pass.
