Improved motion correction

[heckflosse]

I implemented pixelshift in RawTherapee in pixelshift branch and tried 3 methods.

1. method is the one from dcrawps
2. method uses a 3x3 grid
3. method uses a 5x5 grid

In almost all cases 2. and 3. outperform 1.

In case you want to have a look, here's the source. It's source for RawTherapee, but should be easily portable to dcrawps.

There's also a discussion in rt forum

Thanks. I will place it on my todo list, but it might take very long before I work on it.

No problem at all. I'm also still working on a better motion detection...
