Preview templates in files

[Schrank]

At the moment it is only possible to preview templates which are saved in the database. It would be great to preview "standard" templates - the ones which are saved in /order/email/...

I guess Marc, Tobi or me will not implement this anymore...would you still like to do it or is it ok to close the issue?

I think PR #19 which I'm processing at the moment might be what you are looking for.
