After wiki page update/addition a notification mail is generated. This mail contains localized message @:mail_body_wiki_content_updated@ with interpolated html link to wiki page (@:id@ argument).

Currently, this generated message is treated as html unsafe and thus all tags are escaped. The workaround is to call @html_safe@ method on localized message. Attached patch contains implementation of this workaround and unit tests covering this issue.

Please let me know if there is a better solution.
