_ExcelSheetAddNew() abends if specified sheet already exists

[Spiff59]

The _ExcelSheetAddNew() function abnormally terminates script execution with a COM error if called specifying a sheet name that already exists within the workbook. Also, after the error, the workbook will erroneously contain a new generically named sheet ("Sheet 1", "Sheet 2", etc).

The following change adds a loop to check if the sheet is already in the workbook, and kicks out a new @error value (@error = 2) if found.

I suppose I could have made the @error = 2 test a single-line If/Then statement, if anyone cares...

That function doesn't follow its specification regarding return values.
If you want to submit some code then either do it correctly or don't do it at all. I understand the desire to be useful but please don't do it by adding new bugs.

I'll close this as "Rejected", and I'm hoping you will report it again, only correctly next time. By correctly I mean with explanation of the bug, reproducer (where is it now?), and suggestions if you have any.

Oh, the SetError() returns... shame on me.
Leaving it as rejected works for me.
