adds python port (only simple projection)
allows to have range_cutoff > range_max NOTE this is required if we need to keep the range_max readings in the point cloud. An example application is an obstacle_layer in a costmap.

Added .count field (of 1) to every PointCloud2 field description. This fixes the bug referred to here: http://dev.pointclouds.org/issues/821 which is useful because that fix in PCL seems not to be released yet. Also this way is more correct, as far as I can tell.
Tidied up CMakeLists.txt based on Dirk's recommendations.
