Title: Allow passwords with non-alphanumeric characters to be entered

I'm not 100% sure that this is the most failsafe way to do this, but it works for me. Any data provided by the user in the app's UI (username, password, SKU) are now surrounded by quotation marks.

To test this, try entering a password containing a ")" character.
