whether a physical sensor needed to be active or not was managed by a simpe reference counter; unfortunatelly nothing prevented it to get out of sync if a sensor was disabled more than once. sensorservice already maintainted a list of all the "clients" connected to a physical sensor; we now use that list to determine if a sensor should be enabled. This can never be "out-of-sync" since this is the only data structure linking a sensor to a user of that sensor. also removed the isEnabled() method, which was never used and implemented wrongly (since it didn't take into account that a sensor could be disabled for a client but not of another).
