Drawables and menus don't exist in ics-openvpn

I don't copy images nor menus nor layouts, because we don't want to use ics-openvpn UI.

We need to decide what to do with those classes which make use of them. Discarding them (i.e. not copying initially) may provoke problems with some needed classes, I need to see if we can filter unused (by us) imports and clean the dependency graph.
