Bracketing sequence suggestion

[shawl]

I would like to suggest that two new bracketing sequences be made available: 0, +, + and 0, -, -, etc. I have found times when such a sequence could be helpful. Making these available should be trivial to do, I'd think.

This is already possible with the current implementation in the cameras.

So if I want 0, +2 and +4 bracket I set the camera to bracketing with 2-stops and offset the exposure compensation by + 2 stops.
