Suggest ontological terms - Bohuslav's part

[tomas-knap]

Supplement core DPUs with the possibility to suggest ontological terms to the user when writing SPARQL queries (Req 47), it will use ontologies from the designed area.

We will provide special TextBoxes, TextAreas and ComboBoxes, which will have the ability to suggest ontological terms

Allocation:

Bohuslav: prepare special TextBoxes, TextAreas, ComboBoxes. It should work in a way that when "[a-z]+:[a-z]" is written, it suggests the terms from the given ontology. When further chars are written after [a-z]+:[a-z], the suggestion starts to be more focused (8h). Suggester calls Jirka's method, see #299
