e4 - Dependency Injection Tooling

In bug 302824 we started discussing how to make the use of DI easier and beside e.g. providing Helper-Classes the ideal thing would be to provide good tooling. Think about how hard OSGi-Development would be without PDE and I think the same is true for DI as well. I had some free minutes (well in reality hours) today and thought about how such a tooling could look like. The first thing I've implemented today is a dialog showing core services and add them to your POJO (currently only the UI is working more or less). There are other JDT/PDE extension we could provide to make DI in general easier but I need to make myself familiar with PDE/JDT-extensions before I know what's possible.
