Add -fPIC option for 64 bit linux machine compatibility.
Move drawing functions out of planning::RRT and into app drawRRT
Merge branch 'master' of github.com:dartsim/dart
Create DART_INCLUDE_DIRS in DartConfig.cmake

Copy DART_INCLUDEDIR into DART_INCLUDE_DIRS variable, which
matches cmake conventions.
Fixed APIs to determine the max number of contact detected. Fixed bugs in FCLCollisionDetector. Now DART supports sphere-mesh collision via FCLCollisionDetector (you can switch the collision checker in ConstraintDynamics from FCLMeshCOllisionDetector to FCLCollisionDetector), though FCLCollisionDetector does not support other types of primitives.

Remove DART_INCLUDEDIR from CMake files to force users to use the more standard-compliant DART_INCLUDE_DIRS
Improve support for out of source builds, fix urdf linking

There are many places where temporary build files are installed
into the source tree ${CMAKE_SOURCE_DIR}, when they should be
installed to the build folder ${CMAKE_BINARY_DIR}. Also, I was
having trouble finding the urdf libraries, so I fixed
