Jets Bundler

Bundler extensions for Jets.

This helper method is used to define a component (engine) as a dependency when using a shared Gemfile.lock for all engines.

It does the following three things:

• Define the comoponent as a dependency for :default and its own named group (gem "component", path: "engines/component", group: [ :default, :component ]).
• Loads the component's Gemfile.runtime if any to the same groups (eval_gemfile "engines/component/Gemfile.runtime).
• Adds all development dependencies from the component.gemspec only to the component group (gem "dev-dep", group: [:component])

This patch helps to avoid Bundler warnings regarding duplicate gems. It checks whether a Gemfile has already been included and skip it, if so.
