Subject: [PATCH] Builtin/falling: Add fallback vector in case of nil
'wallmounted to dir'
The fallback vector is in case 'wallmounted to dir' is nil due
to voxelmanip placing a wallmounted node without resetting a
pre-existing param2 value that is out-of-range for wallmounted.
The fallback vector corresponds to param2 = 0.
