Store/load settings in URL

[synap5e]

It would be useful to be able to pre-populate options via a URL fragment or parameters. e.g. https://correcthorse.pw/#capatailze=true,digit=true

Specifically this would make it more attractive to link the site in documentation/comms to users when suggesting they use this site to generate a password for a service with a password policy that e.g. requires a capital and number.
