Rails_xss Plugin

I installed the rails_xss plugin, for
the main purpose of seeing what will
break with Rails 3.0 (where the behaviour
of the plugin is the default). I think
I've fixed everything, but let me know if you
see stuff that is HTML-escaped, which
shouldn't be.

As a side benefit, we now use Erubis,
rather than ERB, to render templates.
They tell me it's faster ...
