fix ill-guided linking of the DummyPlayer facade object type info

DummyPlayer is experimental code,
but actually we've established the convention
to linke the facade-proxies into common/interfaceproxy.cpp
note some unresolved problems with our DummyPlayer
resolve the remaining liblumieracommon.so dependency problems

now this library doesn't refer to any symbols from
Proc-Layer anymore. Resolving these problems
highlighted IMHO a serious shortcomming of our
interface system, which hinders the building
of abstractions at interface level
