bumped to version 0.2.0

a) finally got the gamma correction sorted for basic manipulations and
icc conversion, also for 'good' and 'bad' Imagick-versions

b) have outsourced all methods returning info about the servers Imagick
setup into a separate class "ImagickInfo". All its methods can be called
statically.
