Update docs for img_as_ubyte
...
The line in `img_as_ubyte` needs correction; ubyte cannot hold negative data. From a quick experiment it seems like both `img_as_uint` and `img_as_ubyte` clip negative values (and not shift them to the positive domain).

Docfix for img_as_float; appended myself to CONTRIBUTORS
...
img_as_float() 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.
