Fix for documentation for RC_CHANNELS_OVERRIDE. See Github issue #72.
Replaced all occurances of 32767 & 65535 with INT16_MAX and UINT16_MAX. This makes it more clear that these aren't magic numbers. Additionally implies that the macros INT16_MAX/UINT16_MAX are to be used, which should be available in stdint.h.

Override fix
Updated HIL message specifications to better meet demand, added helper functions to convert between Euler, Quaternions and rotation matrices (DCM), following NASA rotation standard and originally written (as attributed) by James Goppert.
Added copy step for conversions header, reverted HIL_STATE to original state, marked it as deprecated and added HIL_STATE_QUATERNION for the intended long-term message
