Utilize Environment Variables to set Dependency Versions

[parkr]

@benbalter This should allow for easier testing. E.g.:

$ PAGES_JEKYLL_MENTIONS_VERSION=0.0.7 bundle install
# installs all gems, with jekyll-mentions bumped to 0.0.7

Or, just update one:

$ PAGES_JEKYLL_MENTIONS_VERSIONS=0.0.9 bundle update jekyll-mentions
# updates jekyll-mentions to 0.0.9

@parkr I have updated my gist once again. Now it really looks clean and simple: https://gist.github.com/ixti/990f53e9d693ae075ea1

Why not have a single bit that, once flipped, initializes the DEPENDENCIES constant, but doesn't actually require add the gems to the gemspec? Testing would require you to implement any dependencies in a vanilla Gemfile?

Well, this is what we do now. And we have a ton of dependencies. Unless there's a really easy way to put all of them into the Gemfile, it would be far too tedious to rewrite all of them individually in the Gemfile.

If the .gemspec is converted into YAML when the gem is built, this won't work. 😦
