First Release of the gwt-esri library

I have pushed the first release of the gwt-esri library. I have chosen to start at 0.5 because 0.4 just sounded depressing and I have actually pushed 4 other jars before this one. I have all the major classes to the Js Api's 2.1 spec and have documented all of the classes. TODO's still include the ServiceArea task, Virtual Earth support (guess I can't be ALL google), as well as better dojo support. Several of the dojo classes are just placeholders at the moment. Finally, I am sure the library full of bugs which I am hoping anyone who actually uses this library helps me find and kick out.
