generalize "paginator" component

[tomachalek]

• the location should be views.common.index
• there should be 5 callback defined in props - first, last, prev, next clicks and direct value change (this one should be optional)

additional note: Please change the returned object form from
{AjaxLoader: AjaxLoader} to {AjaxLoader} (i.e. skip value variables in case they're the same as respective keys)
