snaptool should not allow live edits to config file via web page by default #37
Description
By default since v1.6, snaptool now allows anyone hitting the web page to make live edits to the config file, no authentication even required. This can be disabled via the --no-edit command-line argument, but that is arguably a dangerous default! Why not reverse this behaviour: do not allow unauthenticated edits by default, and only enable this behaviour when explicitly asked for, such as with a different command-line argument (--edit, --allow-edit or some such).
