I don't think this function returning "HTML" or "urlencoded array" is great and should not land in this format the PR, but it served as a quick demo.

We should be able to get "plain text" and "HTML" versions of form submissions, which then carries it all the way down to how file upload fields, multi line text fields etc get rendered.

Plain text can then be used to render plain text version of the full email as well, for those clients that instruct not to get HTML versions.

Then we can use plain text in emails and just wrap it in urlencode().

$compiled_form = array();
$response = Feedback::get( $feedback_id );

Might need to check for URL length limits here.

Ideally this HTML table gets moved to HTML template, and actions becomes more lightweight; either just link tags or URL+label.

Now we're starting to split HTML layout in two different files which isn't great.
