Import a template from the Import Resource template tab and apply data in Editor tab

[jgreben]

Fixes #394

Removes the old "StartingPoints" box from the Editor tab and enables the new "ImportFileZone" box on the Import Resource Template tab. Once a file is uploaded and validated it will read the loaded data (same as before) but now it will redirect back to the Editor tab and set the Editor tab's state with the loaded template data.

The new text for the Import File Zone:

Loaded file and schema validation:

Redirect back to Editor tab with loaded data:

question: will we be adding a list of links or a dropdown of starting points to the import tab, or don't we care at the moment?

I have some questions -- it may be that they are all about concerns that have already been addressed with the current code base and the refactorings in progress.

@ndushay this is what the design from @astridu looks like. To me it seems like the import profile div and the standard profiles div would be separate components, the latter rendered below the one I renamed.

There's a new design for the page where user can select a resource template to use. I'm not sure if it is in scope, but the users would like a table listing all the profiles, their IDs, and who it is associated with. @jermnelson @michelleif Is this correct, or are we reverting to the old design where it's just a list?
