Create bioformats_package.jar (rebased onto develop)



This is the same as gh-882 but rebased onto develop.

----

The Ant 'tools' target and default Maven goal will create both jars.
bioformats_all.jar is the union of loci_tools.jar and ome_tools.jar;
bioformats_nolog.jar is the same as bioformats_all.jar, but without
slf4j-log4j and log4j.

The primary motivation behind this is to have something that can work well with OMERO.insight-ij (i.e. bioformats_nolog.jar).
