Subject: [PATCH] fixed resizing issues when having long comments: * embed the
 comment label inside a scrollarea * assure that the "add comment..."/"change
 comment..." link is always visible * assure that the maximum width of the
 meta data widget is set to the panel width (otherwise the panel would be
 increased in an unlimited way when having a text without spaces)
