It is enabled by default, users have to specifically ask for it if they don't want gamepad support. If libudev or libevdev are missing, the build aborts and tells the user the reason and that they can disable gamepad support with the "gamepad=no" option.
Test if clang is defined in CC/CXX/LD - this allows a specific version of clang to be defined
move appending -DTYPED_METHOD_BIND to keep clang options together
move sanitize option out of use_llvm test, gcc48+ also supports sanitize=address

-Moved drawing code to a single function that takes linked list (should make it easier to optimize in the future).
-Implemented Z ordering of 2D nodes. Node2D and those that inherit have a visibility/Z property that affects drawing order (besides the tree order)
-Removed OpenGL ES 1.x support. Good riddance!
-Fixed many bugs in stretch mode
-Fixes to camera project and unproject as consequence of the above
-added setget to script (documented in script doc)
-more fixes to collada exporter for blender

Build System:
-Big clean up of SCons, changed how builds are done to a much cleaner method (check the Github Wiki for instructions).
-Deactivated BlackBerry10 (sorry), if no mantainer found (or BlackBerry does not send us a Passort ;), platform will be removed as we have no longer devices to test.
Engine:
-Removed deprecated object and scene format (was in there just for compatibility, not in use since a long time).
-Added ability to open scenes even if a node type was removed (will try to guess the closest type).
-Removed deprecated node types.
