(suggested by Berndinox in #205; been bugging me for a while too)

Currently, the Docker image exposes port 80. We should change this so that running Meli doesn't require root access.

We'll need to update the deployment docs.

Documentation Updates:

• Add prefetchPages property description.
• Add security notice on requests that a user can fire any request on a page. We block requests on a page level, so a user is only allowed to fire requests which are included on the current page.

Mohammed Ali Agha commented the change is understood but not needed as they've already adjusted

Actually there are some themes but I think they need some improvements in the CSS, mostly the neumorphic ones.

Any new theme is welcome, neumorphic or not
