Convert Excel date

I'm working on an Excel importer library, so I've been doing dates as 
well. Date conversion and Excel-style date/number formatting options are 
needed anyway behind the scenes for import, so my plan is to make them 
available as functions too. (I will also support dates further back on 
Windows, if LiveCode doesn't extend the built-in range.)

Best wishes,
