Output the dependency versions for this build of Pages.

[parkr]

This allows easy access to the Gemfile bundler directives, which may
be easily used to tweak versions for upgrades, etc.

An alternative to #71.

Usage:

Individual dependencies

$ bundle exec github-pages versions

github-pages gem git directive

$ bundle exec github-pages br [branch_name]

Using in your project

$ bundle exec github-pages versions | pbcopy
# comment out the gem "github-pages" directive, replace with contents of clipboard
# bump versions of gems you're interested in.
$ bundle update # does it work?
$ bundle exec rake test # does your app/site still build with the new versions?
$ # if it all works out, go submit a PR to pages-gem.

@benbalter Gem dependencies can't actually be modified at runtime... SO making it easier to get all the directives was all I could think of.

An alternative to this is to say github-pages <branch_name> and for it to spit out:

gem "github-pages", :git => "git://github.com/github/pages-gem", :branch => "branch_name"

Anything to make it easier to bump.

IMHO this does not belong here. It should be in bin script directly.

👍

Perhaps github-pages versions or something similar to give us an entire namespace, rather than a unitasker?

@benbalter Done!
