Instead of single mpk_text widget for each ks and changing the contents
when switching, create an mpk_text widget for each ks and switch between those.
This allows putting the "show xpub on device" button inside mpk_text.
It is ugly that the 'channel' callback takes a wallet I guess,
but with channel backups in one wallet, and active channels in another,
it was causing problems... (when open simultaneously)

* Add --fingerprint option
* Simplify conditional checks
* Improve warning wording
* Throw error instead of logging and returning
* --fingerprint => --serverfingerprint
* Only run fingerprint checks against main server
* Throw error if --serverfingerprint is set for a non SSL main server
* Fix linting errors
* Don't check certificate fingerprint in a seperate connection
* Disallow CA signed certs when a fingerprint is provided
* Show clear error and then exit for Qt GUI users
* Remove leading newlines from error dialog
* Always check is_main_server() when getting fingerprint
* Document how to generate SSL cert fingerprint
There is a standardised location along with reserved hotkey for "Preferences"
in applications on macOS. Let's put *another* preferences menu item there.
The duplicate items ensure that
- an electrum user coming from a different OS,
- a macOS user used to the standardised preferences location,
will both find "Preferences" easily.
