Big oversight in my previous commits: Widgets need to be able to have specific configurations (i.e. the path for different instances of the "disk" module has to be different). To account for that, it is now possible to assign an "alias" to a module instance using ":" (for example: -m "disk:home"). This alias is then used for the configuration parameter resolution automatically, for example: -m disk:home -p home.path=/home As a consequence, parameter names in the module code are now relative to the module, which means: shorter!
