Merging of the NewForm, EditForm and DispForm editing experience

In a lot of use cases, NewForm, DispForm and EditForm are almost exactly the same. This means that effort is duplicated - a change is made to one, and has to be made to the rest.

In practice I am changing one form, and then navigating to the mFormsStoreLibrary and manually copying the JSON to the other two forms.

I would suggest the ability to only use one json file to power all three, without having to copy each time. Then, within the form, I can simply customize behaviour by using  [[@Form.IsDisplayForm]],  [[@Form.IsNewForm]] and  [[@Form.IsEditForm]].
