String Value Binder Allow Setting "Ignore Number Stored As Text"

[oleibman]

When String Value Binder converts a numeric value to text, the resulting spreadsheet will be full of little green triangles to indicate to the end user that something might be wrong. It is unlikely that a spreadsheet created in this manner needs that visual clutter. This PR adds a property and setter (I can't really think of a good use case for a getter) to suppress it. Suppression should arguably be the default, but, for now, I will avoid any BC problems by leaving non-suppression as the default.
