* NEW: g:vimwiki_menu option is a string which is menu path. So one can use let g:vimwiki_menu = 'Plugin.Vimwiki' to set the menu to the right place.
* NEW: g:vimwiki_fold_empty_lines -- don't or do fold in empty lines between headers. See :h g:vimwiki_fold_empty_lines
* FIX: Encoding error when running vimwiki in Windows XP Japanese. Thanks KarasAya.
