Remove most of task evaluation code from Task class, rely on Task::DSL.evaluate to get an evaluated task. * Task: remove #evaluate, change constructor prototype to accept actions instead of a block, implement .evaluate(name, env &block); * Implement Task::DSL.evaluate method; * Recipe::DSL: remove tasks evaluation from#evaluate, modify #task to use Task.evaluate to return the new task to be rigstered.
