Debounce form submissions

[tjrivera]

Users have the tendency to double-click a button when saving or submitting a form, because of the nature of some form submissions (REDCap specifically) We're likely to have two requests submitted to our backend before the first is finished processing. This may also have an adverse effect on other datasources.

Possible solution may be to set the disabled property on the submit button(s) to true when the XHR is greated and set it back to false when the XHR is done
