Issue XD-3321: Make requirement for MD5 hash files configurable for the custom module registry 
Post 1.2 upgrade, the custom modules no longer show up by just copying the jars to the {{xd.customModule.home}} directory. Instead I have to use the 'module upload' command to install the modules. This is because an MD5 file is required. More details in [SO thread|http://stackoverflow.com/questions/31792220/spring-xd-1-2-0-custom-module-deployment].
