etcher/scripts/desktopintegration
Juan Cruz Viotti f683b841fa Make use of AppImage desktop integration script (#346)
This is useful to prompt the user to install the `.desktop` file.

The `Description` key in `Etcher.desktop` was changed to `Comment` since
`desktop-file-validate` complained with:

    Etcher.desktop: error: file contains key "Description" in group "Desktop
    Entry", but keys extending the format should start with "X-"

After checking the desktop file format specification, the correct key
should be "Comment"
(https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s05.html).
