Updated resister values with those from the prototype

A few final tweaks

Initial re-layout of the Hotstick Wand.

Finished change for 0402, also generated fabrication data

Changed 0402 to sod-523 for Zener

Removed reset pull-up (should not be needed as internally pulled up) to make room for the heat detect logic and layed out the remaining components for the heat detect.

Removed the capacitor from the Temp sensor to allow it to be centred and initial modifications to allow monitoring of when the tip is being heated.

Initial PCB layout, still work in progress.

Connected the MPU interrupt, needed by the http://www.i2cdevlib.com/ library for the MPU-6050
