Update the pom.xml:

* I updated to a new versions of pom-scijava (1.162 -> 4.2)
* I had to add a version for ij (no longer managed by pom-scijava)
* A version for jama is no longer necessary (now managed by pom-scijava)
* I added a property to add an underscore to the name of the jar file
* A link to the issue management was added
