Issue #1707: Add documentation to api-docs.viewsets

Updated documentation for urls.py

Updated quick start project set up order

Trivial doc updates

Add test for SerializerMethodField

A view's action is dependent on the request method. When overriding the method (e.g. to generate a form for a POST request on a GET call to the browseable API), the action should be updated as well. Otherwise, viewset functions may be in a weird limbo state where a 'list' action has a POST method.

+ Explicitly specify module names in the standard format similar to all
the other tutorials
+ Remove the extra quote around module name

Fixed small typo in docs

ModelSerializer.restore_object - wrap ValueError error in a list

When a ValueError is raised in ModelSerializer.restore_object, the error
is set to a one-element list, rather than a bare string.
