rename state updater and remove duplicate.
allow versions controller to render json-show.
add status_tag helper and use in in info/versions

status_tag wrap the status-helpermethod. It provides
the information which is necessary for the automatic
polling status updater.
adjust automatic state poller

state poller should now be functional again.
prevent poll-implosions for automatic state-update

Instead of calling enqueue inside of the loop (so for every turn every
element gets a new enqueue for all elements, we enqueue updates
element-wise.

Later on we could even further optimize that by using
ontology_version_id to only poll for each version once per 'tick'.
