cvsnt 2.0.11

On NT, make notifies case insensitive (can't do the same for edits,
unfortunately, due to the way they're implemented).

Fix behaviour of import sometimes falling over.

Release from outside a sandbox wasn't detecting changed files
properly.

This is released earlier than intended because the import problem
seems to be hitting a few people & my inbox is filling up :)
