initial work on id site implementation
moved api key live test to test_resource module
added live test for building id site redirect uri
add live test for handling id_site callback
add doc strings to id site methods
exclude tests package from setup.py
typo fix
Merge branch 'master' into id_site_impl
make sure id site methods don't require specifying an api key

The apiKey in this sense is the apiKey.properties being used to
configure the Client instance and connect to stormpath (not a user
Account.ApiKey instance like originally implemented).
Fix bad merge of PR 44

Add refresh method to resources/collections.

This enables us to, for example, call client.applications.refresh()
after we have deleted one application so that we can refresh the cache.
Added Mock and Httpretty tests.

Fix cache issues. Make sure we always use the cache when accessing object data.
We assume the cache is fast.
