[Lazarus] New Excel Interface Component

Yes, definitively,

I've checked, this code seems to be currently geared to use DISPID 
interfaces. This works in Delphi, but not in FPC for the time being.

For example, the following code:
   fDocument := fDesktop.loadComponentFromURL('file:///'+ 
StringReplace(FileName, '\', '/', [rfIgnoreCase, rfReplaceAll]) , 
'_blank', 0, wProperties);

declares fDocument as an OleVariant. The author hopefully expects FPC to 
understand how to go and fetch "loadComponentFromURL". It ain't gonna 
work ;-).

It should be done this way:
   var fDocument : IDispatch;
   fDocument.InvokeDispatch( DISPID_LOADCOMPONENTFROMURL, ...);
