* Add Standalone Password Generator. Closes#18
* Add an entropy meter for passwords. Closes#84
* Don't require password repeat when it is visible. Fixes#27
It's loosely based on OS X PasswordAssistant. Generation happens as soon as a
change is made, and on open of the widget. A combobox has been added to allow
one to choose from some randomally-generated alternatives, and the UI is
generally been made a bit more compact.
