Add a "greyed-out" style for disabled buttons.
Having looked through the templates for examples of usage of this
I'm not convinced that we should really be showing disabled buttons.
I think in general it would be better to hide or show a button
based on whether the action is available.

I agree, I think hiding or showing is better, but this patch is
harmless enough, until we want to go fixing our usage
