Merge pull request #16 from hybridgroup/artoo.io-new

Task 56 - Adding new design improvements to website
Changed code samples to Inconsolata and Ruby 1.9 syntax.
Cleaned up URLs and finished converting code samples to 1.9 syntax

Changed URLs:
  - /documentation.html -> /documentation
  - /examples.html -> /examples
  - /supported_hardware.html -> /hardware

For now, the old pages have been converted to redirect to the new URLs. These
can likely be removed in time.
Add rake to bundle so all's self-contained
Correct stylesheet link for non-root pages
Adding fork me on github
