Extended the protocol in order to building IRIs' autocompletion, via keywords/text research

[BorderCloud]

This autocompletion of IRIs does not presuppose any prior knowledge of the SPARQL service and the ontologies it contains. The user writes keywords, in the language of his choice, to obtain a list of suggestions for relative IRIs. It is then enough to choose one so that the SPARQL editor can insert it in the current request. This type of feature is requested by all kinds of users. For the moment, I use the Wikidata API to build the demonstrator of this autocompletion but ideally, all SPARQL services should offer this research of its IRIs when it's possible [1].

I would call this searching for IRIs, not autocompletion. YasGUI has autocompletion

• write a prefix, type colon. Its taken from prefix.cc (or in GraphDB, from the repo namespaces) and added on top of the query
• type some chars, press control space. The appropriate term (class or property depending on context) is auto completed.
