Subject: SERVER-13874 Make mongo::Milliseconds et al. aliases for equivalent
 stdx::chrono types.

Also introduces operators for adding stdx::chrono::duration to Date_t,
subtracting two Date_ts to get Milliseconds, and remove the use of
reinterpret_cast from the implementation of BSON Timestamp type.
