fix goto definition when inbetween tokens

Browse source 
fixes both goto_definition and goto_type_definition.
before, when running goto between some non-trivia token and an
identifier, goto would be attempted for the non-trivia token.
but this does not make sense for e.g. L_PAREN or COLONCOLON only for
IDENTs. now only IDENTs will be searched for in goto actions.
