Show bionics in character creation, show "None" if no items

Resubmitting the PR after getting rid of hiding traits/skills. Addiction section is still hidden when no addictions are present, as it was previously. Additionally, the items section will now show "None" if it's empty, and respective translation/formatting strings have been added.
Oh, they're not? I thought that translation strings were supposed to go in there. They don't strike me as something that can be auto-generated. E.g. the "%1$s (%2$d)" values in concerned file aren't in the source code.
