Subject: [PATCH] [IMP] mail: keep multiple spaces in chatter and chat

In chat window, a chatter and discuss, the text zone appear as a pure
text zone but is transformed later on in HTML to add mentions links and
possibly other features.

Thus, when we wrote multiple spaces or a space at the next to html tag,
with how html worked they were collpased into one (or zero).

To keep them, we need to wrap the content with `<pre />` tag or replace
spaces with `&nbsp;`.
