Fix:Debug messages now uses the new serial formal.
clean up among libraries
We only need one constructor for the gateway sketch.
Simplify gateway code (handles interrupts internally) and remove external dependencies. Ledmode is now always "enabled".
Remove unused libraries.
Add default CS/CE pin to Config.h
Add new variebles for voltage and current.
Add new internal command sent to controller when gateway is ready and online
Merge branch 'development' of https://github.com/mysensors/Arduino into development
Fix a few warnings in MQTTGateway.
Move all gateway examples to "examples" to work better with codebender and Arduino IDE.
Ledmode is always enabled for gateway. Still optional to connect the wires though ;)
Move MsTimer to local utility folder (no external dependencies).
