Experiment: Remove character whitelist for tag names.

Browse source 
I have always felt bad about forbidding unicode in tag names,
but I want to make sure I have a grip on sanitization / preventing
abuse before allowing it. I think stripping control characters is
enough and any abuse can be handled manually.
Of course that's all fiction because there are no users except myself.
