Issue #5: Some users have reported behavior similar to http://jira.grails.org/browse/GRAILS-9016.  To avoid this (I hope), change the package name for all groovy code to not match the packages in the core metrics jars.
Fixed Issue #6.  Qualify the static strings used in the super call from GrailsAdminServlet.
Paperwork to create the 2.1.2-4 release of the plugin.
