#4 Replace xobjects library

[Spicerun]

Replace the Xobjects library with an LGPL Alternative.
The original library used is copyrighted by
Aleksandras Gluchovas, but there is some question as if
this code has been really released to the GPL
licensing. Since there seems to be no way to contact
Aleksandras, this code needs to be replaced by an LPGL
equivalent (or an LPGL equivalent needs to be coded).
