Updated scijava-common to 1.0.0 release

Depending on SNAPSHOT jars produces non-reproducible builds. All
projects should now use the most recent release of scijava-common:
1.0.0.

Updated the pom-scijava version to facilitate moving to the field
and groupId variables for scijava-common, instead of hard-coding them.
Updated sezpoz to use pom variable

The sezpoz dependency in scifio-devel now uses the sezpoz.version
declared in pom-scijava, to keep jar versions consistent.
