[FEATURE] Static Pages

[jdabtieu]

Is your feature request related to a problem? Please describe.

When creating some basic web challenges that don't require a backend server, it's time-consuming to have to set up a server dedicated to hosting one or two pages, or adding a page to an existing server. Also, after the contest is over, the page dies.

In particular, for bts22, I had to hijack one of my old web servers and add two pages to it, and because of firewall shenanigans, it wasn't accessible from the school network.

Describe the solution you'd like

There should be some sort of admin page to create static pages with unrestricted html/css/js

• make sure the unrestricted js does not pose security issues, perhaps with a sandboxed iframe?
