Access key authentication.
Use the sqlalchemy session as an in-request cache to reduce number of db hits.

Note that we need to use an actual UUID object when looking up the object by a key.

May want to be more explicit about which objects are kept around in the future (something like zope's request.hold() )
Remove unused code.

Use passlib for password hashing. Secret access keys are now hashed using the crypt_sah512 scheme for compatibility with Linux /etc/shadow and .htpasswd.
Allow unix_disabled passlib scheme
Give each collection its own Item class to enable specific view registration.
fixes for feature #205
update target behave test since we deleted link
Building blocks for revised top nav with subnav bar.
Use my branch of pyramid for now.
Add context manager for execute_counter.
More access key stuff. Still need to override the view so that the password hash is not returned and add more tests.
