replace tags UI with a single input field
add logging to new edit_tags method
integrate tag-it library into tags field
Fiddle tag widget behaviour to not quote tags containing spaces, to match js tag-it's behaviour
Steal tagit styles for the non-edit tag display
alpha-order tags, so they appear in the same order in edit and display modes
AJAXify the add-tag action
AJAXify remove tag action
make tag forms work on graphics/music pages too (oops)
Focus the tag input when putting the tags panel into edit mode
implement autocompletion on tags
slugify all tags, to avoid duplicate tags with different capitalisation
Now that tag names are URL-friendly, use those in URLs rather than slugs (because slugs can sometimes have _1 suffixes left behind, and are missing dots)
Add a TagDescription model
Display tag descriptions as popup bubbles in tag listings
Ensure that graphics / music have their tags in alpha order too
actually, I like the 'productions tagged: Foo' title better
add a hint on the tag description field to tell people not to go overboard with the length
better HTML title for the productions-tagged-with page
