remove blank from FAQ name

Hello,
If I create a new FAQ with blank character between text and question mark, the FAQ page contain some space.
By example: "My FAQ ?" will be name "My FAQ++++++"

To fix it, you must replace this line of FAQCode/FAQHomeSheet:

#set ($question = $stringtool.stripEnd($stringtool.trim($!{request.question}), '?'))

by

#set ($question = $stringtool.stripEnd($stringtool.trim($!{request.question}), ' ?'))
