dgarijo/Widoco: WIDOCO 1.4.12: Big fixes and new configurations

This version of WIDOCO addresses the following issues (thanks to @pmcb55 for his contributions!!) #354: The page would display centered in the visualization instead of the element loaded. #362: Upgraded to latest version of OWL API #361: Allowed adding a "-uniteAllSections" flag that will print all sections on the same document. Hence, dynamic loading will be removed. Tidying up PROV rendering. Small typo fixes in the default htm
