Replace clade/assembly dropdowns with a search bar on most CGIs. Add a recents list to hgGateway and to the species bar and to the 'Genomes' dropdown menu. Track recently selected species in localStorage. Add toGenome and fromGenome arguemnts to hubApi/liftOver in order to find appropriate liftover assemblies, refs #36232
