Martin Gräßlin db9368fc26 Merge the code to render Client's and Deleted's decoration in SceneOpenGL
The code was basically copy'n'pasted to handle both Client and Deleted
requiring to cast the Toplevel to both Client and Deleted to test whether
it is one of those.

This is now changed from runtime to compile time polymorphism. A
templated method is used to start the rendering process for the decos.
This on the one hand simplifies the code and on the other does not
require any dynamic casts any more as we use the available check on
Toplevel whether it is a Client or Deleted.
