I did not know this. How do I use the template?

The most recent release won't build because it expects a dependency
that no longer exists. I do not know which of the thousands of commits
since then fixed that issue so, I cannot easily generate a patch. It
follows that the best choice is to use the most recent commit, which I
can confirm does not have that critical issue.

I added a comment to explain why I specify the most recent commit. I
also added a note that it should be updated when the next stable
release is available (the maintainers seem to prefer announcing new
releases every September). I will personally update this in
mid-September or October if version 0.4.8.1 or 0.4.9 or 0.5 or 1.0 is
available and no volunteer beats me to it. If you want I can also
request release 0.4.8.1 ASAP so we can specify a release rather than a
commit. I personally prefer to keep the commit and wait three or four
months for the release.

The link says that 4X refers to a genre of strategy game centered
around conquest. I think the current context is a sufficient
explanation, but I did expand the description. I think it is best to
keep the 4X in the description in case someone tries a search for that
genre.

I added comments to explain these licenses.

Updated patch is attached. Is there anything else you want me to fix?
