Recursive xdelta diff tool

Ruby tool which can compute a recursive diff between two
directories, producing a patch directory, and also can
apply a patch directory to take a directory from one
version to another.
Unit Test framework for xdelta diff tool

Uses the Ruby unit testing framework to have unit
tests for the recursive xdelta diff tool.
Add functionality to diff zipped directories

Rather than diffing two directories, we now add
functionality to first zip two directories, then
compute the diff between the two zipped files.
This should make the diffs we send smaller.
[endlessm/eos-shell#1991]
Merge branch 'xdelta-work'
Fixed paths from scaffolding generation
Moved tests into proper location since we're not using rails
Moved Rory's work to proper directory. Still not tied to the gem
Added _spec to suffix of the tests so that rspec will pick it up
Extracted some of the mehods into a util. Need to add/fix tests
Made the tests run (though with errors)

  Old Rails tests were causing issues but I got them to work in the new env
  though they are all showing broken state. Next step is converting them to
  RSpecs
Got the initial rspec framework ready

  Also deletd some superfluous functions from utils since they wrap the simple
  built-ins without much reason.
Ignoring temp test files
Added test for the taring and untaring util methods
Removed out extracted utils from the main class
