[vdr] skincurses in vdr-1.5.9 broken

Hi Klaus,

when trying to compile the new vdr, skincurses reports the following error:

make[1]: Entering directory `/dvb/vdr-1.5.9/PLUGINS/src/skincurses' g++ -g -ggdb -O2 -Wall -Woverloaded-virtual -fPIC -c -D_GNU_SOURCE -DPLUGIN_NAME_I18N='"skincurses"' -I../../../include skincurses.c skincurses.c: In constructor `cCursesOsd::cCursesOsd(int, int)': skincurses.c:76: error: no matching function for call to `cOsd::cOsd(int&, int& )' ../../../include/vdr/osd.h:247: error: candidates are: cOsd::cOsd(const cOsd&) ../../../include/vdr/osd.h:259: error: cOsd::cOsd(int, int, unsigned int)

It seems that there is an modification for the new level-osd-feature missing.

Regards, Joachim.
