Rebrand Eclipse.app for Mac OS X

The release for Mac OS X has a JBoss Developer Studio.app that includes nothing more than a shell script which launches the Eclipse.app. This creates a disconnect between the icon/name the user clicks to launch the application, and the icon/name shown in the Mac OS dock and menu. A better solution is to scrap the existing JBoss Developer Studio.app and update/rename the Eclipse.app so that it has the JBoss Developer Studio branding. An alias can be created to the rebranded app in the eclipse subdirectory from the top level jbdevstudio directory.
