Force all content types to default to making a revision

It would be nice to have a module to force all content types to make a revision by default.

Optionally force all content types to make a revision period (no option for the user to uncheck "Make a new revision".

And (really optionally) provide a central administrative spot to toggle these for all content types listed together (rather than having to edit each content type to default to revisions or not, and the ability to force revision would be new).
