Merge pull request #85 from FellowTraveler/master

Merge C++ rewrite of Chai high-level API
Added a few missing changes for the Chaiscript to C++ conversion.
Also: depending on ot_me_switch.hpp setting, OT_ME.cpp will no longer
load ot_commands.ot and ot_made_easy.ot when running in C++ mode.
It will add direct references to the C++ equivalents of the Chaiscript
functions to the Chaiscript interpreter instead.
Move success status of ot_test to right before “press enter” so it is
directly visible
