In many cases it's safe to assume the load path will be setup correctly
at runtime, eliminating the need for absolute paths. For instance, in
your bin/synx executable, RubyGems sets the load path such that you can
just `require "synx"`. When you use RSpec, it also sets the load path to
allow you to use `require "spec_helper"`.
I also cleaned up the `File.join(File.dirname(__FILE__)...` stuff to use
the more idiomatic `File.expand_path`.
The `colored` gem was replaced with `colorize`. It has a very
similar API but comes with a few extra methods to remove or check
colors.
The Tabber class has had an options hash added to it, to make
further additions easier.
