Small wrinkle just turned up here, ICU only does parse/format for base 10 
numbers and not for binary, octal or hex, which is technically correct as they 
are not localised formats, but it's a pain none-the-less.

Because QLocale, QByteArray, QString and QTextStream offers the base option in 
the public API, we will need to keep the existing code to do it.  If the 
requested parse/format is for base 10 then we'll pass it to ICU, otherwise 
we'll use the current code.  We will just need to document the behaviour that 
other bases will always use the standard digits and not the local one.
