Fix wiki secure config automatically

[rossjrw]

Whether a wiki is http or https is set as a bool flag on the remote config. When a wiki changes whether or not it's secure (which is rare but happens), this is breaking because Wikidot will only accept requests with the correct protocol. The fix is that I have go to the config and switch the flag, but only after having observed the error at least once.

Instead, the notifier account could do this edit for me when it hits such an error.
