several minor changes

detector response function: C example removed gmodule dependency
all headers: removed glib.h include for G_OS_WIN32 in favor of _WIN32
mac os x: reverted to Tango! had to do with gdk-pixbuf2 build option
--disable-gio-sniffing which needs to be active for us
mac os x: bundle now also contains all headers and fortran module files
detector response function build improvements
