The bug triggered if
- we store two parsed_option object into variables_map
- the options descriptions associated with those parsed_option objects
are different
- an option present in first parser_option object is not declared in
second options_description.
The problem was that on the second 'store' call we went over all
stored options, trying to get their description from the *second*
options description object.
Thanks to Hartmut Kaiser for the bug report.

as opposed to having his own data structures. Clean up option description
classes a bit, removing unneeded methods. Remove support for 'implicit'
options.
