Lens Presets function

[Armadill0]

Add a possibility to have lens presets. This could either be done by a lens list which could be found on the internet or by a lens setup page like the camera setup page.

The first possibility presume a very good and preferably complete list. The latter one is a simple solution which needs some time for the user to setup, but also searching lenses from a long list on the depth of field page would take much time. So maybe the lens setup page should be the preferred solution.

Both solutions should be integrated with the possibility to choose the options manually.
