Saving in admin

[Jernej Golja]

When clicking "save all" under System-settings, some sort of overlay image/text should probably be shown to notice user that something is happening.

There should be "Success" bootstrap growl, there's none for you?

The same issue is with tabs for which content is loaded from the ajax call (some product editing tabs in admin for example). Some sort of "loading" box should be displayed with a possible return status (at least for errors).
