Gave cpplint proper errors.hpp-before-boost include order logic.
Fixed include order style warnings (caused by changes made to require proper errors.hpp/boost ordering).
Put BOOST_NO_CXX11_RVALUE_REFERENCES in errors.hpp to silence bad boost compilation errors.
Unmarked some unused-marked variables (that were only temporary unused while bisecting a compiler crash).
Merge branch 'next' into sam_377
Moved BOOST_NO_CXX11_RVALUE_REFERENCES definition to the Makefile (putting an assertion of its presence in errors.hpp).
