Subject: [PATCH] Support for tagging of actions!

Made a start on tagging support. You can add tags via the action forms (just single word tags, separated by a space so far), update tags via the edit form (same limitations), and also search for all actions with a particular tag:

/todo/tag/[tag_name]

Tests for tagging are a bit rudimentary at the moment, and you can't as yet use tags consisting of multiple words, or search for conjunctions of tags (e.g. foo+bar), but I'm hoping to add these. Also no validation, so don't try anything funny!

I'm also planning on letting the user create custom links to /todo/tag pages, so that you can use a tag for inbox, someday/maybe, today, a meta-project, priority, or whatever you like.
