Contact us with full site SSL does not redirect to https if http entered

[mc12345678]

In How do I enable SSL after I have installed Zen Cart? it is stated that if a store owner wishes to set their entire store to SSL that ENABLE_SSL should be set to false; however, in such a condition a customer could enter a non-https address to reach the contact_us page and it would be first "provided" as http. When ENABLE_SSL is set to true and such an address is entered, then the site redirects to https.

While this condition requires a user to make that entry, it would seem that the same treatment should be offered for the full site set as SSL as is performed for when SSL is enabled just for the necessary pages.

This type of topic has been discussed a few times as a "debate"; however, it was today that I realized this issue existed. Most recently discussed is: https://www.zen-cart.com/showthread.php?221740-How-can-I-change-all-links-in-the-store-to-be-https-if-the-site-accessed-via-https

Just to point out what is perhaps obvious. The contact us page has been treated somewhat specially in that the includes/modules/pages/contact_us/header_php.php file actually has a redirect in it to provide a more strict application/presentation of the page being provided as https than other "similar" pages. Ie. the login page does not have a similar redirect in it, but does pushes the information securely regardless of the entry point to the page (url being entered as http or https).

This particular commit does not (yet?) expand to that and other similar pages but addresses only the contact_us page because one might expect the same behavior whether ENABLE_SSL was true or if HTTP_SERVER included https and ENABLE_SSL was false.
