Title: Docfix for `img_as_float()`; appended CONTRIBUTORS

The `img_as_float()` function in dtypes.py had a legacy note stating
conversion would force negative values to the positive domain; this
no longer described its functionality. Note changed to reflect the
retention of negative values when converting from signed datatypes.

When submitting my multichannel improvement to the random walker
segmentation algorithm, I neglected to append my name to the
CONTRIBUTORS file. Now fixed.
