Release 12

• Fix tags from Zerochan not being retrieved (thanks to issue #20)

• Added a new window under Settings > Boorus > Zerochan where some namespaces can be mapped to custom names.

Zerochan has the usual namespaces like "series" or "character" but also less common ones like "artbook" or "studio". Previously those were arbitrarily renamed, like "studio" becoming "creator" after parsing. Now you can choose what name should be used for those.
