Added lambda feature for onMessage callback. Fixes #147

[rcarle3911]

It allows the use of lambdas to access class reference. For example.

client.onMessage( [this] (String &topic, String &payload) { Serial.println("Member Variable: " + String(this->myVar)); Serial.println("incoming: " + topic + " - " + payload); });

Thanks for contributing this! As you can see from the Travis logs the "functional" library is not available on all Arduino platforms... We need to add some macros to remove the code on platforms that do not support it. Would be able to look into that?

Sure that should be easy enough
