Versions not being marshaled into a Ticket object

[lgleasain]

Ben Langerfeld and I noticed that the Versions which gives you the history of the ticket is not being marshaled into that object. The Lighthouse API appears to be returning it, but ActiveResource doesn't appear to be handling this correctly. From what we can tell it looks like either the API return should be fixed or a different method should be used to un-marshall the tickets.
