Saving a post/page should no longer create an empty Ninja Forms custom post meta.
Fixed the get_subs function so that it works properly with dates in formats different than m/d/Y.
Fixed a bug that caused response message fields to be output if multiple forms were on the same page.
Fixed a bug that caused hidden fields to not show up on the submission edit screen.
