Kickoff & Menu Editing

Currently, our launchers have a "Edit Applications…" action. This opens KMenuEditor.

As a context menu for launcher entries, there's also an action "Edit Application…", which opens the properties window for the .desktop file ("General" tab, not "Application" tab).

I suggest that we instead open KMenuEditor with the entry. This would seem more sensible as it's a bespoke tool for this task specifically. It supports arguments to open something specific, but some changes might be called for to make this easier.

With this, I'd also suggest changing the launcher action to "Edit Menus…" to distinguish it from editing a single entry.

"Launch Menu Editor…" wouldn't work with these suggested changes, as we would have two actions for editing a specific application or menus in general that launch the application.
