Bleeding edge UPnP service discovery :

Bleeding edge UPnP service discovery :
 * depends on CyberLink C++ UPnP library available from :
   http://sourceforge.net/project/showfiles.php?group_id=89768
   with iconv compilation patch from :
   http://jserv.sayya.org/upnp/clinkcc170-fix-compilation.diff
 * requires libexpat-devel or whatever you call it,
 * needs review by playlist guru (Zorglub ?),
   especially as regards locking
 * at least, detects UPnP Media server properly
 * I'm looking for a '''working''' UPnP Media Server on Linux for more
   extensive tests. I couldn't get TwonkyVision to accept my medias :(
 * tentatively closes #98 - and probably introduce new bugs
