(svn r7468) -Codechange: [win32] Add some comments to MB/WIDE_TO_WIDE/MB_[BUFFER] macros and 

use them some more in win32 code. Also for the clipboard use the convert_from_fs
 function instead of calling Win32 API directly. Make the static buffers in OTTD2FS
 and FS2OTTD the same size (character-length wise)
