Fix QLocale::standaloneMonthName when d->m_data == systemData()

At the moment if d->m_data == systemData() it calls
systemLocale()->query but forgets about the standalone part
so you get the wrong data

This patch introduces the new enums so that backends can implement
properly the standaloneMonthName feature properly. At the moment the Windows
and Mac ones still return the monthName, the Unix and Blackberry ones return
the data we store in months_data.

Fix creating new QWS surface only when it does not exist already

Calling createSurface(const QString &key, const QByteArray &data)
function is needed when starting/creating new server/client
application, and changes to region sizes (and memory allocation)
after that is handled by QWS surfaces themself inside
setGeometry(const QRect &rect) function.
