v0.5.0 - Deep and Light Sleep Implemented

It is now possible to run GrowNode with batteries!

I've just finalized the testing of Deep and Light sleep management. You can find a dedicated page on reference guide.

This is useful when you just need to record values from your hydroponic system at a specific time, like humidity or temperature. On a DevKit board, the power consumption i've recorded in deep sleep mode is around 15 mA, that means you can run your board for months without changing batteries.

Of course many other improvements are made, imcreasing reliability and reducing bugs. you can find them in commit log.
