[#7593] use nl2br in audit log rendering

markdown rendering was causing problems with some project audit log lines like:
`updated "post" permission: "*authenticated" => "*authenticated, *anonymous" for tickets`
which contain `*` and was causing italics.  It also was adding some white space
and seemed to make long audit logs take a little longer to render.
