Bug 22744: Remove the 'do not notify' buttons

These checkboxes are simply a way to clear the prefs before editing. We are not saving
a lot of click, and we are confusing people, this patch simply removes them

To test:
1 - Edit a patron's messaging preferences
2 - Think too hard about the 'Do not notify' boxes
3 - Feel confused
4 - Apply this patch
5 - Edit a patron's messaging preferences
6 - Confirm it feels better
