stack parameters marked as hidden should use a password field

[Miguel Grinberg]

In the launch stack form, any heat template parameters that are marked as hidden are presented as a regular input field, exactly the same as a normal string field.

Given that hidden fields are marked as such due to their sensitive nature, it would be better to use a password entry field for them.

How to reproduce:

1. Use the following template:

heat_template_version: 2013-05-23
parameters:
  password:
    type: string
    hidden: true

2. Note how in the Launch Stack form for the above template the "password" field at the bottom shows characters as you type them.
