Ontology not automatically created

[Zerskk]

a new ontology should be automatically created in the database, if a new ontology file is committed.
At the moment a new ontology row is manually added in the database table.

[Zerskk]

• ontologies are now created automatically by adding and committing after that with "git add".
• ontologies are now removed automatically from database (and belonging terms in Term table) by removing and committing with "git remove".
• example configuration file updated. [file] section not required anymore.
• ontology name is obtained from ontology file
• there is currently no method to obtain a description.
