Problem with gene search typeahead

[tonydisera]

From Barry:

was unable to review the gene TNN. When I would type that gene symbol in the app I would get a drop down with many possible completions, but all of the completions available were partial matches to TNN and came alphabetically before the actual TNN gene and so the drop down list did not contain the actual TNN gene. I was unable to scroll down past the visible matches to TNN and there was of course nothing more I could type that would limit the list further, so I couldn’t figure out a way to view TNN. Could we make either that you can scroll through the list of all possible matches in the drop down, and/or make the matching so that exact matches appear first in the list

Use new async service rather than genes.json to decrease memory footprint and enhance search capabilities to return aliases.
