Also translates the first arg if it's a symbol and adds more btn- classes if given as html_options[:type]

Just in case some translation keys are not present things should still work and make sense.
So translation keys should be picked in a meaningful way and scoped rather than prefixed.
For example overview.account will turn into "Account" if no translation is present while "overview_account" will turn into "Overview Account". We usually want the former.

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

To use bitmask services:
Download Bitmask

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)

Feature/api quota support + current_user null pattern

let's devide the partials rather than having super specific parameters (on_user_page)
