Changed Sensor to Device 

Please review and test it

* Removed .settings, .project, .classpath, and target folders ---> I will kill someone if I have to remove it again... XOXOXO
* Added licenses (NOTICE.txt file) and removed MIT license
* Generated java files for the http://srv-ustore.haifa.il.ibm.com:9060/universAAL/OnlineStoreManagerService/OnlineStoreManagerService.wsdl for being compatible with java 1.5

Updated models some details of middleware and service models, and revised phThing (still incomplete)

Updated validation script to use rule names that do not conflict with the transformation script, and to return if there are errors or not (ignoring warnings) from the checkModel 

Added a warning comment for default context publishers, because clumsy developers who have not read the documentation may make the mistake of not adding a ContextProvider. You cannot really call this an "update", so no problem if it doesn´t get released.
