Possible Feature Envy in Room.java to MXDataHandler.java

[bemica]

The method sendEvent in Room.java makes most of its calls to mDataHandler, an instance of MXDataHandler, suggesting that sendEvent, or some functionality thereof, might belong in MXDataHandler

sendEvent uses a lot of private fields in Room, so refactoring sendEvent to MXDataHandler would require exposing these fields, which is undesirable. On this basis we decided to leave the method where it is. Another potential fix would be to move the methods in MXDataHandler that sendEvent uses to Room.
