Revert e42bb97 - add links to Tuakiri guides

Revert e42bb97 that was removing links to the User and Admin guide.

Reintroduce the lines in _loginform.gsp

Modify messages.properties with links to Tuakiri versions of the guides.

Refactor the templates.aaf.vhr.loginform.help.account message - instead
of just the "Create Account" text, this messsage string now contains the
whole HTML line, including the link target (now also pointing to a
Tuakiri-specific URL).

Revert "Remove user guide and knowledgebase links from login form"

This reverts commit e42bb97990533405287a30f762908a8f071578b1.
