First pass at merging John's project/apps into mine. Added isLive field to JSON.

TRx_question_app project merged with the trx project. Questions app
merged with trx_app app. The trx_app/views.py became api.py in order to
keep the config web views and the api views separate. Still need to
delete all the obsolete files. Added isLive to JSON DB model.
Merge cleanup by deleting obsolete files
