just before feature freeze, I've committed some changes to program_options:

- the command line parser was refactored. For historic reasons, it has its own
data structures for representing options, and now it uses the
options_description class. The internals were also cleaned up.

- the 'implicit' option flag was removed. I've asked for comments on this some
time ago, and no objections was raised.

- some methods of 'options_description' and 'option_description' classes were

- In 1.32, the 'additional_parser' could return only a single option. There's
a new method of command line parser -- 'add_style_parser', which can be used
to specify a function that can return vector<option>. This might be
convenient, for example, for parsing response files

Except for 'implicit' removal, those changes should not affect users of the
library. However, I'd appreciate if user test the new version and report any
