Bump version to 2

There have been quite considerable changes since version 1.
The conversion tools have had a considerable performance boost of
around 75% by using a row-buffer instead of reading each R-G-B-A-chunk
individually.
Also, 2ff(1) somehow called "xconvert" instead of "convert", rendering
it useless for anything other than png's and jpg's.
There was a small excursion to color spaces and ICC color profile
handling, but this has been dismissed (it was a difficult decision).

Thanks for all the feedback!
