arm-ttk does not flag default passwords

[raouche]

arm-ttk version: 0.24
Scenarios:

1. A PasswordBox control has its defaultValue set to a certain value.
2. A CredentialsCombo (Windows or Linux) control has its defaultValue.password set to a certain value.

Problem: arm-ttk does not flag the default password scenarios like it does with the UserNameTextBox even though the default password instances are far more dangerous than the default username.
