Update to latest pom-loci (and latest pom-scijava)
Bring license URL link up to date
Make scifio dependency compile-time

Eclipse does not differentiate between compile-time and runtime
dependencies, but they are different concepts, and command line Maven
will refuse to build if a compile-time dependency is declared as
runtime-only.
Use "loci-legacy" instead of "loci-common"

While loci-common continues to work for backwards compatibility,
the current name is loci-legacy, so we may as well update it.
Use latest version of cppwrap-maven-plugin
