avr-gcc on Travis-CI

I wanted to build an Atmel AVR project on Travis-CI. This wasn't hard at all: Ubuntu ships a usable gcc-avr package.

I uploaded a sample project as a demonstration. Here's the .travis.yml:

language: c
  - sudo apt-get update -qq
  - sudo apt-get install -qq gcc-avr binutils-avr avr-libc
script: make

Open firmware is one of the reasons I bought my FlySight audible GPS. Open firmware means I can hack on it, sure, but it also lets me use world-class tools like GitHub and Travis-CI.
