Right now KMenuEdit has no AppStream metadata and has NoDisplay=true set in its .desktop file. This means that most of the methods for a user to find the app don't work. If the user doesn't have it installed but searches for it using Discover, no results will be found.
However this app is a useful, user-friendly GUI app and there is no real reason why it should be hidden in this way.
This commit makes it visible, adjusts its metadata a bit, and gives it AppStream metadata so that it can be found by app stores like Discover.
