Password variable for service catalog

I was asked to add a password field on a catalog item and I was appalled
to find this isn't an out of box variable type. I went ahead and made a
widget to make one that is secure but I feel we shouldn't have to.

So in my case I wanted the following;

• 2 Masked Password fields that verified they matched and that they
  match a regex expression.
• Store the password as a encrypted value so I can
  use is later but keep it secure.

Here's the end result;

To make this follow these steps;

1. Make a variable type of string, variable name of password.
2. Make a variable type of macro with label, variable name of
   password_macro.
3. Make a Service Portal Widget with these values;
