Install from GitHub (#170)

* Update installation instructions in README
* Update version to 1.6.0

1.5.0 is already released and typically @apokalipto bumps the version right before releasing.
However, since we're updating installation instructions to use Github directly, we should bump the version so it's obviously newer than what's on rubygems.

* Pin byebug for older versions of Ruby
