Fixed scifio-tools pom.xml

Updated the scifio-tools pom.

To test:
run "mvn" components/scifio-tools and verify the "groupid" typo
run "mvn" from top-level and verify scifio-tools is not included in the build
import scifio-tools into eclipse and verify "missing loci-common" component error

You could also manually add scifio-tools as a module in the top-level pom to verify the version mis-match.

All the above should work after applying this patch.
