dynamic_bitset:
* clean up and fix of copyright notices for the include files that are directly under boost/
* parenthesized a couple of macro names in boost/dynamic_bitset/config.hpp
(yeah, a bit paranoid, I know :-))
* removed some superfluous comments and enclosed an url in angle brackets
* changed block_width_type, to avoid a few level 4 warnings with MSVC++
* added the usual private-and-non-implemented copy members to bit_appender
* removed useless #pragma warning(disable:4996) for MSVC++ (it should have
been eventually applied to much more places than it was; and, anyhow, the
only sensible way to get rid of the warning is to disable it globally)
* slight tweak in to_ulong (assert moved a bit earlier)
