[e861587] Split up show_comments handling

Currently there are two classes that have the
class show_comments. I renamed one to
"back_to_stream_element_top" as it is responsible
for scrolling the user all the way up to the top
when clicked. The other which toggles the
reactions will remain as "show_comments".

closes #6004

This new class replaces all existing server side message
rendering helpers and is the new global entry point for such
needs. All models with relevant fields now expose an instance
of MessageRenderer for those. MessageRenderer acts as
gateway between the existing processing solutions for markdown,
mentions and tags and provides a very flexible interface for
all output needs. This makes the API to obtain a message
in a certain format clear. As a result of centralizing the
processing a lot of duplication is eliminated. Centralizing
the message processing also makes it clear where to change
its behaviour, add new representations and what options
are already available.

Remove stray console.log. Not skipping CI because I think this may be causing the cucumber failures.

This fixes issue #2032.  Anyone can now view all comments on a public post without needing to log in.

Leaving the #order call in #last_three_comments caused the generated SQL to
have two conflicting ORDER BY components, which caused the query to return
invalid results.  I removed the problem by removing #last_three_comments which
I consider a premature optimization.
