Revision 176796

- link wiiremote eventclient with -lbluetooth (link-bluetooth.patch,
  fixes build)
- fix some cases of libpng15 being used instead of libpng12, causing
  XBMC to fail to start due to conflicts between libpng12 and libpng15
  as some parts were built against libpng12 (as they do not build with
  libpng15)
