Started adding implementation of client-side functionality.

- Changed ts_api:dispatch_user/3 to return information for the user currently,
  authenticated if a valid session id is presented and no username is presented.
- Moved the generic styling of form > * elements to be specific to .bar > form.
- Added jQuery U 1.8.0.
- Created login dialog that will automatically load upon page load if the user
  is not logged in.
- Added styling for jQuery UI login dialog.
- Implemented login functionality on the client page.
- Implemented functionality to load user and timeline records on the client
  side.
