You-Got-Phished email & Dynamic Login Webpage added

[Script-Nomad]

The "You-Got-Phished" pretext uses an all-image email template that is best utilized with the message padding plugin in order to overcome spam filters which target emails with an insufficient text-image ratio. The pretext preys upon users in organizations which actively look for phishing emails or undergoes significant training. The pretext focuses on users' concerns that they fell for a previous phish and redirects them to the landing page.

The message should be formated simply using an inline_image as follows:
<a href="{{ url.webserver }}">{{ inline_image('/path/to/you-got-phished.png') }}</a>

Note that if you utilize a remote-image, and a user's email client does not automatically load remote content, the image will not render. In this instance, it may be beneficial to create a backup pretext in the alt parameter of your img tag, hence why inline_images are recommended.

The Dynamic login page simply uses jinja tags to generate the user's name & pre-fill the username with their email to make it appear as though they have visited the page before. Additionally, if a company logo is supplied in the `./images/logo.png` file, it will be rendered at the top of the login portal to add to its legitimate appearance.

Worked hard on this one. Hope it gets used 🥂

@zeroSteiner Noticed this was sitting in my PRs for a while. Is there anything that needs to be done with this further, or is it good for merge?

[zeroSteiner]

Yeah, we'll just need a review from someone. @securestate/king-phisher any takers?
