Improved dialog centring

Password requests from the tx dialog box are now centred on the
tx dialog.  Similarly for error messages if misentering the password.
Also, "Signing transaction..." and "Broadcasting transaction..." are
centred on the appropriate tx dialog.
Finally restore the old "Sign" button enabling / disabling, as we
can now tell if the user cancelled the password request.
