There was a lot of special case handling going on in the users_controller
for this. Lot simpler this way.

Hiding them using two mechanisms in case one fails:
.hidden class - bootstrap hides them then
style='display:none' - so they are hidden even if css load fails

the loading... text on the buttons was not capitalized before.

So in order to change this in a (more or less) single place i added
new button types to simple_form:

button :wrapped - normal button, with loading and an optional cancel button wrapped in the classical bootstrap action div.
    cancel option contains the url to go to when canceling.

button :loading - simple button with loading text capitalized by using i18n (simple_form.buttons.loading)
