Remove unused avrdude lib.
Remove bower components folder

Instead of including the components in the repo we now
use the built in package manager that comes with bower`
to manage and version lock deps.

This introduces another step in getting started, which
is to run bower install.
Vendor bower to make the install process painless.

This allows people to not have to install bower globally and instead
run bower from npm.
Abstract getting started into into a readme.
