Make View Account Statement more usable

[laushinka]

The View Account Statement feature in the Admin dashboard is currently not readable, and even copying the JSON to a clipboard is painful because of a lack of scrolling.

	No UI at all, just return a content-type JSON response, and a content-disposition header so that you can save it it in a file.

The JSON response should be downloadable.

Would there be a download button? Where would it be? @jldec @gtsiolis
Or instead of "View Account Statement" it becomes "Download Account Statement"?
