Launch process in terminal emulator if required
If a desktop entry requires a terminal, but the current process does not run in one, the process would previously run invisibly in the background. Now we instead start the process in a newly launched terminal in that case. This is especially useful when (for example) opening text files downloaded in a browser using the system open dialog. For now the terminal emulator to be used is specified in the configuration file. When/if there is a standard way to select the terminal emulator, it is conceivable to use that method instead or if no config item is present (see https://gitlab.freedesktop.org/xdg/xdg-utils/-/issues/84).
