Convert double to int when decoding via gson

Refactored MapDoubleAdapterFactory, extracting DoubleConverter to be
used by code needing to convert Double to Integer/Long after being
decoded by GSON.
Enhanced StandardCoder to automatically use the above converter if
the desired class is a generic Object.
