To use super dev mode:
1. Be sure the project sdk version is GWT 2.7
2. Start a web server first
3. Start the code server, mvn gwt:run-codeserver
4. goto sdm code server web page and copy the bookmarklet, this will start the sdm to compile.
4.5 or instead of the bookmarklet, add the sdm program arg -launcherDir and point it to the path to the war output directory where the application is getting hosted
5. goto the web server address and push on the SDM bookmarklet
