AvancedSearch:add a new search type for chromosome entities

[pierrelarmande]

Add a new search type for chromosome positions.
Similar to the last pattern query of the SparqlEditor : Retrieve Oryza sativa japonica genes on chromosome 1 whose start position is between 1000 and 30000.
the return result will be a list of genes entities with ID, Label, URI, Name, Description (need to check the extact terms of predicates)
That suppose to

• have a list of taxon label to be selected by users
• select the chromosome id or number within a list
• enter the coordinate start and stop (or start only) (check the predicates)

optional :

• possibility to add a second similar search on a different chromosome positions.
