Update to v094r21 release.

byuu says:

This updates ruby to return shared_pointer<HID::Device> objects instead
of HID::Device* objects. It also fixes an ID bug where joypads were
starting at ID# 2+, but mice were also set to ID# 2. I also revised
nall/hid a lot, with getters and setters instead of stabbing at internal
state. I didn't yet patch nall::string to safely consume nullptr const
char* values, though.
