Make bulk updates to tasks on projects

[#1]

We have a need to be able to post the same update on certain tasks in multiple projects at the same time...task name is the same on every project. This would make our Marketing team VERY happy!

It would also be very helpful to select multiple tasks on the same project and update those to a percentage of complete, 50% or 65% for example, if several tasks are worked on in parallel by a single person on the same project.
