boost/type_traits.hpp should define 'conditional' in c++ 2011.

From a message posted on the Boost mailing list on February 27.

Template boost::conditional is defined by

#include "boost/type_traits/conditional.cpp"

Indeed, type_traits accepted in TR1 did not included 'conditional'.

However, C++2011 adds it, hence it is expected that when compiling in C++2011 mode, the following include

#include "boost/type_traits.hpp"

would indeed define 'conditional' (by including conditional.hpp for example).

​N2240 also talks of 'enable_if'.

[65575] included it in trunk and merged already to release at least in 1.53. What am I missing?

Looks present and correct to me.
