Using the `_html` suffix in an i18n key is the same as using `html_safe`
on it, which means that translation could potentially be used for XSS
attacks.
The name `safe_html_with_links` was confusing and could make you think
it takes care of making the HTML safe. So I've renamed it in a way that
makes it a bit more intuitive that it expects its input to be already
sanitized.
I've changed `text_with_links` as well so now the two method names
complement each other.
It was not commendable independent so avery email related with a comment on a proposal was not being sent. Removes dependency on debates and makes it commentable independent.
