Made the ontology model searchable with

elasticsearch, implemented basic search in the
controller and build a view with filter options
for it.
There is a scope for each search filter in the

view, the search results are filtered only if
one filter is selected and shows all ontologies
which has the selected attributes.
Each model has a scope which returns the

ontologies which have, at least one, entry
from each model, e.g. all ontologies which are
at least in one project or have one license model,
also each model has a method which gives the
name of the instance and the number of
ontologies which have this attribute, e.g.
all ontologies which are in this project XY.
Deleted the javascript for the gwt search

which is already deleted.
Changed the select from check boxes to radio

buttons because of fixed relations.
