A backend update for cucumis !

Yep I had a couple of hours today to work on a few updates mainly for security matters.

First of all, all site is now in https for security (was done few weeks ago).

Also, passwords used to be stored in clear in database. This is fixed now, passwords are hashed.

And finally a [DELETE SPAMMER] button for admins.

Happy 2019 to all of you!

The visa waiver program is a U.S. government program that enables citizens and nationals from the 38 Visa Waiver Countries to enter the United States for tourism or business purposes for up to 90 days without obtaining a visa. The advantage of entering the United States under the visa waiver program is that you can travel to the United States on short notice without obtaining a visa in advance.
