Add Terms of Service to the views

Align breadcrumbs' style with personal navigation

The font size and the padding top is now the same for both components,
making them fit better together. It also gives us more room in the
breadcrumbs, thanks to the smaller font.

To follow OBS style using rails helper link_to.

Terms of Services are shown on any page of the Webui until a user
acknowledges them.
When there are new ToS the ToS notification message appears again and
the user has to acknowledge the new version.
The show page provides the full text of the ToS, while the notification
message just contains a link to it.

Additionally:
* Terms of Services / announcement can be rendered as markdown.
* The order of ToS versions is tracked via it's creation time.
* The footer contains a 'Terms of Services' that links to the most
  recent ToS, if there are any.

If the li tag is always there, then this partial cannot be called in
other partials without having an extra empty `/`. The partial has to be
called in package#attributes for example (since the attributes are for
packages and projects, under the attribute_controller)

When checking an array with `if my_array`, it will always be true (no
matter if the array is empty or not)

because in development it is necessary to see beta features.
In development beta should be opt out and not opt in.
This got introduced in #5640.

Fix haml offense

Allow users to join the beta, even with a proxy

Users could not join the beta when a proxy is in place. The page to edit
their account (and join the beta) was not reachable.

Fixes #5667

Write html id in 'lisp-case'.

Those are static values. By converting them to constants we don't have
to pass instance variables between controllers and views. It also DRYs
the code.

In addition we freeze the constants to reduce object allocation.
