Disable "deprecated" JDT warnings

[Bananeweizen]

I'd like to disable the deprecated warning in all JDT/PDE project settings of Tycho bundles/modules. That would lead to way less warnings (and the deprecated things cannot be fixed in almost all cases that I checked). Looks like this locally (with a filter applied instead) and would make it possible to actually recognize newly introduced warnings.

DO you men with @SuppressWarning? Would be fine for me if you already have checked that nothing can be done...
