Summary: Add a SEE ALSO pod section

Description:
This section plugin will produce a hunk of pod that references the main
module of a dist from it's submodules and adds any other text already
present in the pod. It will do this only if it is being built with the
Dist::Zilla manpage because it needs the data from the dzil object.

In the main module, this section plugin just transforms the links into a
proper list. In the submodules, it also adds the link to the main module.

For an example of what the hunk looks like, look at the the /SEE ALSO
manpage section in this POD :)
