toaster: toastertables: Clean up and fix up a number of items

 - Remove the unused 'computation' field
 - Remove the code to try to make the tables behave like an api
 - Remove custom JSON encoder in favour of DjangoJSONEncoder
 - Simplify get_data and add comments
 - Add exception type instead of using generic Exception
 - Clean up python style warnings
