hallgren b0a40d82b9 haskell-bind: change the type of CRuntimeFFI.getConcr
Change the type of getConcr from

    getConcr :: PGF -> Language -> Concr

to

    getConcr :: PGF -> Language -> Maybe Concr

This is to prevent programs from crashing later if you try to select a
concrete syntax that is not present in a grammar.
