Orange: more work on float/exr buffers;

- EXR now saves and reads Zbuffers correctly
- EXR reading didn't set alpha to 1 yet when no alpha buffer was present

- ImageWindow: the "black point" only checked for the r value... now is OK
- ImageWindow: Curves panal has button "reset"
- ImageWindow: hold LMB drag shows rgba and z values. With SHIFT or CTRL it
  applies black/white point whilte dragging too
- ImageWindow: saving file copied the entire buffer... removed that. Also
  made the header print clear; this save only saves in own file type.

- Curves: zoom and drag now gets clamped by the Clipping value

- Imbuf: duplicate buffer only copied one quarter of to new buffer
