hexbright.cpp fails to compile on ubuntu 12.04.1 "precise"

[eichin]

Wire.h comes from arduino-core 1:1.0+dfsg-9.

This diff actually gets it to compile, and is enough to make at least tactical.ino actually work on the hexbright...

The Arduino package provided by precise is too old. You need to use Arduino 1.0.2 or later.

If I understand correctly, you are running arduino 1.0? I have verified functionality with arduino back to version 1.0.1

Looking at https://launchpad.net/ubuntu/precise/i386/arduino-core and https://launchpad.net/ubuntu/quantal/i386/arduino-core it looks like Precise has 1.0, quantal has 1.0.1, and precise-backports has 1.0.1. Might be worth noting in the top level readme (quantal is current but precise is LTS, ie the long-term-support version.) Thanks.

I've added additional information on linux setup to the main readme.
