Added custom arguments to the doc decorator.

Existing properties of routes can be overridden by defining them using
named arguments to @autodoc.doc; the only exceptions being rule and endpoint.

As of now, custom arguments shown using the default template are in raw format.

Some formatting touch-ups

Added unit tests for custom parameters.

Shortened some of the unittest names a little bit

Fixed up some indentations in the default template

Updated templates to include the location stuff

Reset default template to bare defaults

Resolve conflict for: Fix autoescaping in custom template example

Added custom properties to the custom example

Removed the unittest for HTML w/ custom params

There are far too many complications with importing an external
template from within our unittest module, and using anything besides
the default template is showing itself as being absurdly complicated.

In order to comply to the request of removing any custom param stuff
from the default template, I am just going to remove this unittest in order
to get it passing again without needing to do some pretty crazy roundabout stuff.
