#2 configure option --oldlaser ignored (0.8.0)

[Arne Groh]

When using the configure option --oldlaser carmen is compiled using the new laser.
When selecting "use old laser y" in configure dialog compilation breaks. When compiling with new laser first, then without "make clean" configure using the old laser compilation will succeed.
