[network-manager-applet/jklimes/team: 4/7] editor: change JSON Team config widget from GEntry to GTextView

[Jiří Klimeš <jklimes src gnome org>]

commit 744f1be253976f62fa33a90e3365ccbb6cf94e97
Author: Jiří Klimeš <jklimes redhat com>

    editor: change JSON Team config widget from GEntry to GTextView
    
    and allow importing the config from file.
    
    libteam configuration is a string that can be quite long and simple GEntry is
    is not much appropriate for it. This commit uses GTextView instead, so that
    structured multiline JSON config can be typed. In addition to that, the file
    chooser button allows selecting a file whose content will be imported as the
    config text.
