Added support for "optional packages". Those can be defined in

HaikuImage and enabled individually using the
AddOptionalHaikuImagePackages rule or all at once by setting
HAIKU_ADD_ALL_OPTIONAL_PACKAGES. In principle an optional package can
be any kind of addition to the Haiku image, but usually a zip file will
be downloaded from somewhere and unzipped onto the image. I've added a
WonderBrush package as an example.
