Small tweaks to compress.rb (optional PNG grid flag, fixed semantic classes for ruby 1.9+)

[nemoDreamer]

ChunkyPNG seems to be flaky on a lot of peoples dev environments, so i made it optional w/ the -g flag. Semantic Classes was using Array's implicit .to_s, which causes a ["...", "..."] output in newer versions of Ruby.

@nemoDreamer It looks like the build is failing - mind getting this working so I can merge?

Will do! Thanks for considering it ;)

Travis seems to be failing on:

$ bundle install --deployment
Fetching gem metadata from http://rubygems.org/.........

Could not find ffi-1.0.8 in any of the sources

ffi is a chunky_png dependency which seems to have had problems around the time I submitted this pull request. I switched to oily_png, as that is generally a good thing to do if you want more platforms to be able to compress.rb their own source.

Travis is failing on:

An error occurred while installing capybara-webkit (0.3.0), and Bundler cannot

continue.

Are you sure Travis ever worked for you? I see from the previous pull-request builds in your queue that bundler was always failing: https://travis-ci.org/joshuaclayton/blueprint-css/builds/3804122

Any news on fixing the Travis config?

[nemoDreamer]

This and all other pull-requests will fail, since the base build in https://github.com/joshuaclayton/blueprint-css/tree/master is broken. Attempting to fix it in #21.
