fixed bizarre compilation problem of MLS on gcc 4.7.2
Merge pull request #24 from bouffa/master

fix win32 build
added an extra typename for GCC/POSIX compilers for Mourad's win32 MLS
fix
if we have an #ifdef for OPENMP when
PCL_INSTANTIATE_MovingLeastSquaresOMP is defined then we need to add the
same when it's instantiated
added extra _OPENMP guards for the surface tests
reverted random_sample code to 03/08/13, as we're not sure yet what the
right patch for it is, and this version breaks other higher level code
fixed a compile problem on older versions of GCC (e.g., 4.2.1 for MacOS)
