Bug#1146016: collatinus: no desktop entry, the program is invisible in menus

[Arumata]

Package: collatinus
Version: 12.3-2
Severity: wishlist
Tags: patch

The package installs no .desktop file and no icon, so Collatinus does not
appear in any desktop menu and can only be started from a terminal. Someone who
installs it from the archive has no way to find it, and nothing in the package
says that the binary is called collatinus.

The contents are /usr/bin/collatinus, the two .qm files, the manual page and
the documentation. debian/collatinus.install has three lines and covers only
the binary, the data directory and the translations.

An icon is already in the source tree, at res/collatinus.svg, so only the entry
itself is missing. I attach the one I use. It validates with
desktop-file-validate and needs two more lines in debian/collatinus.install:

    debian/collatinus.desktop   /usr/share/applications
    res/collatinus.svg  /usr/share/icons/hicolor/scalable/apps

Categories are Education and Languages, which puts the program where a user
would look for a Latin tool. The keywords cover the words people actually
search for, including scansion and hexameter.
