Admin config differ generates spurious diffs for JSON

[amcclain]

Not positive on this but it seems like the differ generates JSON diffs when I would not expect them. Want to see if this is more strict somehow than it should be - or thinking it would be better for JSON configs to ignore whitespace entirely.

I can see the issue with a diff generated for "{"key":&nbsp"value"}" and {"key":&nbsp&nbsp"value"} (Github keeps correcting my spacing hence the &nbsp). However, I don't think ignoring whitespace entirely is the answer. There is a effective difference between something like "{"key": "start date" and {"key": "startdate"}.

I think the thing to do is parse the JSON into JS objects and deeply compare the results.
