Bump to next dev. release.
Extract then copy gcc-arm-non-eabi to avoid hardlinks.

This allows us to install it with Vagrant.
Move into root directory automatically when bootstrapping.
Don't worry about getting sudo password if we are in CI (passwordless).
Avoid exiting bootstrap early if colors can't be changed.
Bootstrap a few missing packages for latest Ubuntu.
Install setuptools in Ubuntu if easy_install is missing.
Revert "Move into root directory automatically when bootstrapping."

This reverts commit 3b0b25fead833a517c2e1b1d544c702f4ce27676.
Make sure g++ and 32-bit support libraries are installed in Ubuntu.
Make sure tests objdir is cleaned regardless of PLATFORM.
Add flags necessary for building tests with latest version of libcheck.
Add a draft Vagrantfile for building a vi-firmware dev. environment.

Install vagrant, then run 'vagrant up' from the vi-firmware directory.
It will provision a VM and run script/bootstrap.sh. Edit code in your
native OS in whatever text editor you want, then "vagrant ssh" in and
run "make" from there.

Progress on #245 - need to document.
Bump Arduino.mk to get an extensible "clean" goal in the Makefile.
Fix typo in docs.
Clarify data rates in binary section of docs.
Explicitly set all Makefile options when compiling binary releases.

Fixed #246.
Add details on builds to README for releases zip file.

Fixed #234.
Remove old hipchat notification token.
Require an explicit PLATFORM to be set when running Make.

Since the 'make clean' goal was changed to only clean the current
platform, I've had the problem a few times where I'm explicitly setting
the PLATFORM=X when I compile, but not when I clean. It ends up cleaning
the wrong thing, and the firmware isn't rebuilt properly.

This would/will be less of an issue when
https://github.com/openxc/vi-firmware/issues/231 is resolved.
Split up the compile tests into long/short versions.

The long tests are really thorough but we don't need to run them every
time, and it makes running the full compilation step locally kind of
annoying.
