dgarijo/Widoco: Widoco 1.3.1: Bug fixes and metadata enrichment

This release fixes several issues and extends LODE to accept more metadata options for defining terms and adding examples. Fixed an issue with the changelog that produced an empty bullet when the domain or range of a property was an union or intersection. Added tests with different ontologies that help inspecting whether a new change leads to errors or not. Extended LODE to accept: prov:definition, vann:example, obo:definition (with the appropriate class name), obo:usageExample, vaem:rationale, skos:definition and terms:source. Extended Widoco to accept terms:bibliographicCitation, bibo:status, bibo:doi and owl:backwardsCompatibleWith If an error is produced while generating the changelog or the evaluation reports, the section is not generated. Before, an empty section would remain. Fixed table of contents not being translated. When generating the documentation of an ontology, if it imports another ontology that cannot be imported for any reason, Widoco will ignore the import instead of failing. Added the possibility to ignore namedIndividuals when generating the documentation through console
