refactoring
Switch to topic branch that focuses on swift-authentication

Add SwiftV1.request helper

Previously, XMLHTTPRequests that needed swift authentication were made
in almost every function and the authentication headers were manually
added.  This made it easy to accidentally forget to auth in a request.

Now we have SwiftV1.request, which will construct an xhr request that
includes the swift authentication headers.
