Added HTTP response to all methods (included commands and updates)
Corrected an error in function executeCommandGet: it didn't return a
value (error caused by me)
Java code was properly formatted

Check if I did exactly what you needed:
Each time a ServiceReference is taken, after its usage, now we remove
the corresponding service reference (with ungetService()).
This happend in:
- the location update method
- the description update method
- getAllDeviceStatus method
- getDeviceStatus method
Now it respects HTTP specification:
it has not to return an empty list when the requested device doesn't
exist or something went wrong (and so the list is empty): it has to
return a "404 NOT FOUND" message!
