QStringBuilder: add operator += for QString and QByteArray
Optimize cases when we have.
string += someString + someOtherString
Avoid the allocation of one temporary string.
Behaviour change:
byteArray += someString + QByteArray("foo\0bar", 7)
before, the array would end at foo because of the conversion to string
