Release
v0-13-1 is out. Turns out I still had a few bugs in handling the author fields, as well as had forgotten to update the version in the plugin.
I also took a first shot at reducing the calls to the Comicvine API, but without much luck.
PS: sometimes calibre gives a constraint error with too short authors name. I am checking on that and will release a fix asap. In the meantime, remove authors from the authors field starting with the shortest name until it stops complaining.
