Brandur e23b57628f Add attribute mass assignment and use it in #save
As detailed in issue #119, we've somewhat unfortunately been allowing
object attributes to be passed in during a #save because we mix any
arguments directly into the serialized hash (it seems that this was
originally intended to be used more for meta parameters that go to the
request).

As also noted in #119, this use causes problems when certain types of
parameters (like subobjects) are used. We're now left in the somewhat
awkward position of either:

1. Removing this functionality on #save and breaking what may be
   behavior that people depend on.
2. Fully support this mass assignment.

This patch takes the second path by extracting a new #update_attributes
method and using it from #save. It's still far from a perfect approach
because keys that have the same name as certain options (e.g. `req_url`)
are not going to work, but it should capture the behavior that most
people want.

Fixes #119.
