export.gff3() adds trailing semicolons to the attributes column #58

IMHO, trailing semicolons should be avoided because some downstream softwares like genome browsers may fail to parse them (as jbrowse2 does, at least) although they are not explicitly prohibited in the current GFF3 spec.

I have submitted an issue (https://github.com/The-Sequence-Ontology/Specifications/issues/28) to clarify this.
