extra field in Topics:Menutext in stead of using the Topic title (sometimes too long for topmenu) for menu buttons.

We would like to see an extra field in topics, that will replace using titles as menu text. This way you can use long titles for the topic and place a short name for menutext.

For example:

NOPCOMMERCE 3.80
Title : "This is a new page with new functionalities"
Menutext: "This is a new page with new functionalities"

NOPCOMMERCE 3.90
Title : "This is a new page with new functionalities"
Menutext : "New page"
