Output of Genes widget - select which columns should be retained

[Hrovatin]

Currently only Entrez ID is exported from Genes widget alongside the original data. To add other information extracted from NCBI one must merge data (eg. Data and Genes outputs from Genes) and then use Select Columns to remove all the unwanted NCBI data (often empty columns). To do this it seems that genes must be in rows in the first place.
However, when annotating genes one would most often also like to know the Symbols and Descriptions of genes (for this the above described workflow must be used). Thus an option could be added to the Genes widget where you could select which columns should be automatically added to the Data output instead of Genes output of the Genes widget.
