Disable all Form submittals on disabled submit button submissions

[manfromjupyter]

STOP accepting Enter key or Submit button clicks while the button is grayed out.

In the JS require for each method require the button not be disabled.

THEN make sure the disable button for all forms is disabled by default for all creation forms (i.e. not edit or delete confirmation forms)

Relates to #639 and readdresses #812 better

TODO as of #851

1. Get all forms to disable the submit button by default if any required fields are not filled out.
2. Get all forms ideally to follow disabled="true"/disabled="disabled not just tack on class"disabled" because the latter is purely cosmetic.
3. Ensure submit buttons are disabled="true"/disabled="disabled for all forms WHILE form is processing/submitting so as to not allow any multiple-submittals.
4. Full audit that all forms needing required="required" get them

Status as of #851
