remove reset columns button from resource grid

since we now have the client settings, we do not need this anymore

also rename the stateid to 'grid-resource'
(we want to establish a convention to differentiate between saved local
storage items)

the whole saveCurrentState logic was not really necessary, so we can drop this too
