WorkbenchStatusDialogManager was introduced in 3.4 but the constructors
took a Shell argument that they should not have. The shell is now being
ignored in WorkbenchStatusDialogManager due to other fixes already released.
This proposal is simply to:
1) Add new constructors that don't take the shell
so people can the "correct" API
2) Mark the two existing constructors as deprecated (as much as it pains
to do so in a newly released class).
