Create bioformats_all.jar and bioformats_nolog.jar

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.
Fix 'tools' target dependencies
Remove bioformats_all.jar
Rename bioformats_nolog to bioformats_package
Merge pull request #882 from melissalinkert/new-jars

Create bioformats_package.jar
