Intelliplug 1.7

Based on orignal intelliplug 1.6 by @faux123, the follow up patch will remove eco-mode completely since we are using this on a dual core device and turning off 1 core permanently can affect performance. The follow up patch will also introduce some modifications to existing intelliplug to suit a dual core device better.
