Updated LAStools to version 20141117.

This version also has been modified so that the Makefile builds a shared library. The full waveform writer has also been modified so that it complies closer to the las spec.
Modified to work with the lates LAStools library

Makefile.am

src/LidarPoint.h
  Renamed some properties to reflect changes in LAStools.

src/Quadtree.cpp
  Added in a free() statement to prevent a memory leak.
Updated LAG so that it prints fence coordinates to standard out.
