Moved top level target symlinks to package jar files to under target/package.
Executable jar files are placed under target/executable with the new target[/lib] directories.
Under top level target, symlinks to *either* the package *or* the executable jars replace what was a symlink to the package jar path.
Allow disabling of the shade package.
ant-bridge.sh by default only builds executable jars, and doesn't package by default, as did the old ant build.xml.
Added a new package_path.sh utility script for other scripts to use instead of anything in the target folder.
