Align MS Project and Excel import and export formats
Importing and exporting between msp and excel is a formatting horrorshow (starting with msp export including timestamps by default). Cleaning the export for updates and comments, let alone aligning the formatting for msp import (no formulas allowed, file must be closed,...) takes too much time. Finally, wizard column IDs should be exactly the same than what user sees in msp columns (ie. Customised longer name). Takes ages to check and/or test that right setup has been configured and stored
