Added the deploy script.

The deploy script is a sample of my current implementation. Simply
add a custom rsync command to make this a working script.

Removed path change from env.rb.

The path variable should be manually set in scripts and programs that
need access to certain programs. In this case, ruby 1.9.3 needs to be
accessible by hackbytes.
