Stasis doesn't specify all of its dependencies in its Gemspec

[orospakr]

Nokogiri, markaby, haml, and albino (at least) are missing.

I run into this same problem if I install stasis system-wide with gem, or I add bundler (Gemfile) to my stasis website project.

(it may be the problem is that stasis' dependencies don't properly specify their own dependencies)
