99/99 Form Types

[martinberlin]

Start making the Form Types for the backend. So far the following:

• Create a Username (After initial login if you don't have one)
• Add APIs (Populater app_user_api)
• Add API integration (ex. set Lat/Long for weather and give it a name "Weather in Berlin)
• Add a Screen (Select Display & Template) Add possibility to Add Api integrations to the columns defined in the template (Need a new Table template?)

Is tied to core/models so I can just keep on working on that branch. This issue is for all the backend part, front end details can be addressed elsewhere

Closing this one since the basic forms that this Issue addressed are done
