ESP8266-PRO power consumption modification

Making a battery powered arduino wifi solution can be bothersome. In most cases a lot of the on board and external components draw too much current, even when not in use.

We will look into modifying the on-board power supply and leds. The on-board ldo typically use 5 mA Quiescent Current and needs at least an input 1.3 v higher than output, making it impractical using it for battery applications. The on-board leds use around 1-2 mA.
