Initial refactor of task dependency system....

Initial refactor of task dependency system. We are thinking about refactoring the task dependency system. Currently is is based on engine properties and a function sent with each task. In this commit, I have added a TaskRejectError that tasks can raise to indicate that the engine doesn't have the required dependencies. For now I have not removed any of the old stuff, but I have added warnings that we might remove the older *_prop* methods in IMultiEngine. See this ticket for more info: https://bugs.launchpad.net/bugs/361419
