Misc cleanups and not crashing on Grails 2.2

This includes some testing that I was doing to get service names de-cglib-munged on Grails 1.3.x, and also making sure that the plugin won't halt startup of a vanilla Grails 2.2 app. It can't find the service declared in the cache plugin which is getting loaded after the profiler plugin. I guess the namespacing in grails 2.2 might be causing services to be added to the spring config later than just the services plugin. I haven't fully fixed that, but for the time being it will ignore any services which haven't been added to the spring config yet.
