cleanup

One thing I didn't do but you should is to move ConfigUtils from grails-app/utils to src/groovy. The name of that folder is misleading. Originally it was intended to contain all of the various smaller artifact types that weren't significant enough to merit their own folders (like domains, controllers, etc.) But only Codecs ended up being put there - there weren't any other artifact types that made sense to have in core. So although you can put utility classes there and they'll get compiled, it's not really how things were designed. Not a big deal though, so feel free to do nothing :)

I also converted your README.md to Grails Wiki format and added it as plugin docs at the plugin portal: http://grails.org/plugin/spring-websocket It's as close as I could make it; the combinations of tables, bold, and monospaced font collided a lot so I had to omit the monospaced font in several instances.
