From now on these static pages:
`/privacy'
`/conditions'
`/accesibility'
`/help/faq'
`/welcome'
have been moved to the DB and can be modified easily by any
administrator in `/admin/site_customization/pages'
Allowing every format is way more than what we initially intended.
I've only added h2 and h3 because h1 is set somewhere else in the page
(like the title), and h4, h5 and h6 are usually not necessary.
