Add a port for Libresonic.

[jlh]

Summary

This port replicates the existing www/subsonic-standalone and
www/madsonic-standaline. The only difference is that the .war file is provided
directly from the Github project. The .war is not unarchived (as suggested in
the ports handbook) as it conveniently works directly with "java -jar" and I
truss'ed it, it doesn't seem to extract anything but read directly from the war
file.

Test Plan

make all
make install
make deinstall

Thanks :-). I wanted to stick to what there's in www/madsonic-standalone actually.

11–14

Move it below options.

51–52

I lifted up next to the first block. I don't know where it's supposed to go. Why is it important, BTW?

[mat]

I don't really understand why you have a pkg-message, and a message-transcoding, and a separator, where they could all be in only one file.

To make it easier for anyone to work on any port, there is a standardized way to write things in a Makefile: Chapter 14. Order of Variables in Port Makefiles.
