Fixed bug #920
Fixed bug #920

From Martin:

Alright... I corrected SDL_SYS_ToDirection in SDL_syshaptic.c in the linux
directory of haptic. Now in all 3 cases the same value is returned, at least.
Therefore now it should behave the same way as on Windows.

I added some comments and corrected the cases SDL_HAPTIC_CARTESIAN and
SDL_HAPTIC_SPHERICAL.
