@d22 What do you think about this?

• I added loading gifs & opacity to the paged containers
• There is also a global indicator in the navbar next to the search field
• Handling is done via dajax wrapper (proxy + template method :horse_racing: )
• I am not shure sure whether this works with multiple pagers on one site (it seems all the paged content is selected by the same class) Need your merged PR to check this.

I am not shure sure

Currently there is an error on the SWID inventory view, because ajaxSpinner is still referenced in swid-inventory.js, but this shouldn't be a problem after rebasing, #282 fixes this.

Do something like this in paging.js:114:

ajaxWrapper.call(Dajaxice.apps.front.paging, callback, paramObject, {'error_callback': function() {
    alert('Error: Failed to fetch "' + paramObject.config_name + '" paging.');
    this.loading = false;
}.bind(this)});
