Class Hierachy of owl ontologies
OWL ontologies now Possible to view the class-tree

if possible to create one there is a class hierarchy
to use this there is a rake task to build the trees
introduce fetch entity tree hotfix.
fix entities-display for ontologies w/o logic.
introduce is? method for logictype and use it.
fix logic.name pitfalls (by using to_s).
switch call of is? on logic to ontology.
adjust class-hierarchy task for failureresilience

For now we just want to read the class hierarchy for
ontologies, which use URI-style class-names in sentences.
This change will add the ability to walk through the ontologies
and continuining if one fails (it provides some error output).
