split acronyms into separate labels, e.g. "stimulated emission depletion (STED)"

[lubianat]

http://purl.obolibrary.org/obo/FBbi_00000334 main rdfs:label is stimulated emission depletion (STED)

there should be also "STED" and "stimulated emission depletion" as labels

additionally, "STED microscopy" is missing as far as I can tell
