Pre-requisites or dependendencies support (like rake)

[ghost]

I'd like boson support pre-requisites or dependendencies support (like rake).

Example (rake):

task :test => [:compile, :dataLoad] do
  #do something
end

compile and dataLoad are tasks and they are dependencies of task test.

Thank you for boson.

I would to :) If I ever get around to it, I would do it as a plugin. Pull request welcome :)
