Allow any two versions of any two pages to be diffed and the output shown inline in a page.

One version old to current version of SomePage [{Diff from='SomePage@-1' to='SomePage'}]

Version 12 to Version 46 of SomePage [{Diff from='SomePage@12' to='SomePage@46'}]

Between current revisions of different pages [{Diff from='DraftSpecifications' to='FrozenSpecifications'}]

And so on...

Of course this should use the configured DiffProvider, or allow it to be specified...
