Group invite reason got lost

[Kristina Hoeppner]

When you invite someone via their profile page, you can enter a reason for them to join the group. That used to be added to the notification they received. However, that is not the case any more and only a generic notification is sent.

To replicate:

1. Create a group.
2. Go to somebody else's profile page.
3. Invite them to the group.
4. Fill in a reason.

Results:
- Expected: The reason shows up in the notification.
- Actual: It doesn't.

The current notification (replicated is the plain text one, but if an HTML one exists) is:

DISPLAYNAME (function) OF GROUP ADMIN has invited you to join a group, 'GROUPTITLE'. Click on the link below
for more information.

See http://DOMAIN/group/view.php?id=1

Suggested updated notification
---------------------------------

Hi FIRSTNAME,

I'd like to invite you to join the group 'GROUPTITLE'.

[This section only if a reason was given] My reason is:

{add the reason that was provided}

Go to http://mahara.anitsirk.wgtn.cat-it.co.nz/group/view.php?id=1 to accept or decline this invitation.

Thank you
DISPLAYNAME OF GROUPADMIN who invited the person
