(everything described here lives in the namespace flightgear::addons)
New classes: Author, Maintainer, and Contact. Author and Maintainer
derive from Contact. For each contact, the following can be defined in
addon-metadata.xml: name, email, and url. See [1] for details about the
syntax and usage policy. Nasal bindings have been updated accordingly,
there are three new ghosts: addons.Contact, addons.Author and
addons.Maintainer.
The enum class UrlType has two new members: author and maintainer. The
Addon::getUrls() method has a new signature:
std::multimap<UrlType, QualifiedUrl> getUrls() const;
because non-empty 'url' fields for authors and maintainers contribute to
the result, and there can be an arbitrary number of authors and an
arbitrary number of maintainers defined for a given add-on---therefore,
std::map can't be used anymore.
Finally, QualifiedUrl has a new field (detail) which stores the author
name (resp. maintainer name) when the QualifiedUrl type is
UrlType::author (resp. UrlType::maintainer). Currently, this 'detail'
field is not used for other URL types, but this could be changed if
desired.
