Changes: (#639)

* Changes:

* When client loses connection to the server through no fault of your own, it no longer forgets your username.
* It is now possible to do /connect archipelago://username:password@server:port or to paste archipelago://username:password@server:port into the connect bar and hit connect, and have both the username/password filled in that way.

* Switch checksfinder client to getting username from url if suppplied by url.

* Correct the print statement
