Fixed SuperDevMode recompilation problem

- The check for isDevMode now also considers com.google.gwt.dev.codeserver.Webserver
(instead of just com.google.gwt.dev.codeserver.CodeServer) because starting the codeserver
doesn't necessarily trigger compilation/code generation in which case the first time we
have to check for DevMode happens during recompilation.
