Short description: DateTime fields not converted to strings correctly using TDS driver

Did:
I have a small test app that uses the TDS driver's formatValue() method to convert a DateTime field into a string, since I was seeing a wierd result from it in a larger application.

Expected to see:
I expected to see the date value converted into a string like "20090616 08:28:37"

Got instead:
QTDSDriver::formatValue() always returns "yyyyMMdd hh:mm:ss"

More details:
The string that formatValue() uses to convert the datetime to a string seems to be causing the problem. In Qt 4.5.1, the format string is "'yyyyMMdd hh:mm:ss'" (with both sets of quotes). This causes QDateTime's toString() method to not interpret the format string correctly. I removed the single quotes, and it started to return the correct value. I had to prepend/append the single quotes to get a string that Sybase would accept for an insert/update call.

A very simple patch is attached.
