Allow using 'command' attribute on <MenuItem> with custom routed commands defined in AddIns. Implemented offset mapping in AvalonEdit. This allows replacing text in the document without removing all text markers from the replaced region. git-svn-id: svn://svn.sharpdevelop.net/sharpdevelop/trunk@4191 1ccf3a8d-04fe-1044-b7c0-cef0b8235c61shortcuts
