Document abstraction levels and code reuse

By default, we now strip images in the 'first_line_in_markdown'
method.  This keeps images from being displayed in the
one-liner of both todo and project activity panels.

Although not currently used, we allow images to be preserved
with the allow_images: true options.

This is based on the discussion in
https://gitlab.com/gitlab-org/gitlab-ce/issues/49653 and the example
merge request found at
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20908. The idea
is fairly straightforward: we define a variety of abstractions, then
state which can reuse which. This should ultimately foster _better_ code
reuse, make it easier to debug problems, and make it harder to
accidentally introduce a performance regression.
