Genbank import-export bug

[aitorbk]

Problem: import correct .gbk file, export genbank produces incorrect genbank file, that can't be processed by biopython.
Versions: reproduced with ICE 5.1.0 and 5.2.2

Detailed problems (All in LOCUS line):
--The part/plasmid part name is used in the LOCUS name, but that name can include spaces.
--The modification date is missing.

Incorrect line:

"LOCUS       conn Bla-B               114 bp    DNA     linear"
Correct line:
"LOCUS       conn_Bla-B               114 bp    DNA     linear   SYN 29-MAR-2017"

Also, if you input a .gbk file that has "ds-DNA", the output is simply " DNA", so information is lost.

Note: github messes with the spaces, so I have included an attached file.
