(svn r2229) - Fix: [ 1188777 ] Non-existing sprite #5125 (presignal). The DOS grf file trgi.grf has 6 less sprites than the windows one. This results in some segfaults for certain sprites. Fixed it by added a dummy grf file consisting ofr 6 sprites and loaded when using DOS gfx at the appropiate place.
