Updating min build for Angel projects, since 10.9 seems to mess with some definitions
Merging in Ben's changes
On Linux, initialize the controller input values to zero.  Otherwise we might
be reading random data from memory, which could cause Angel to see controller
input that doesn't really exist.  Thanks to Dylan Palmboom for reporting the
bug.
The Linux xpad kernel driver, for certain Xbox 360 controllers (e.g.,
wireless), maps the DPAD to buttons instead of axes.  Attempt to support both
mappings.
