Add a "submitting..." message when Submit button is pressed

This enhancement request is to have RSFormPro! automatically gray out the "submit" button or even the emtire display, and show some sort of "Submitting..." message when a form is actually submitted.

We know there is some workaround to do this, but it implies injecting some code from our side, and also to toggle the automatic layout creation off.

We believe instead this functionality shall be available by default, without requiring us to plug in new code or take the layout creation off.

Vote for it :) !
