preview doesn't work

As of now, every type handles its own preview. Which, I think should be handled by the system.

Probably the view template can be used to display preview, but without those edit, history etc. links.

How about something like this:

* view template just displays the page and doesn't worry about adding edit, history etc links, which will be taken care by a view wrapper template.
* edit template just takes care of providing edit form and doesn't worry about preview.
* edit wrapper supports preview using the view template.

fixed on staging.

Now there are 2 new templates viewpage and editpage, which adds the required header and footer.
render.view and render.edit are available in templates as thingview and thingedit.
editpage supports preview by calling thingview.

Shall we also add support to see diff between the latest version and version being edited?

That would be cool.

Anand says this has been fixed - there may be some issues. We need to turn it off on some templates, like i18n.
