Preemptively bump to new release versions

The following changes were made:
* imagej-common -> 0.10.0
* imagej-ops -> 0.6.0
* imagej-plugins-commands -> 0.3.0
* imagej-ui-swing -> 0.8.0

And indirectly from pom-imglib2 -> 3.2:
* imglib2 -> 2.0.1

These new versions are being released due to reorganization of some
packages between components, particularly the merger of imglib2-ops into
imagej-ops, as well as certain related net.imagej packages (measure,
operator and threshold) moving from imagej-common to imagej-ops.
