add script to build KiCad on Ubuntu/Debian/Mint linux

#!/bin/bash

# Install KiCad from source onto a Ubuntu/Debian/Mint compatible linux system.

# The "installing pre-requisites" step is the only "distro dependent" one.  Could modify

# that step for other linux distros probably.

# Set where the 3 source trees will go
