Added new functions to QTextCodec that accept ConversionFlags.

In some cases the user might want to pass initial conversion flags that should
be used by the QTextEncoder and QTextDecoder, so added convenience
QTextCodec::makeDecoder and makeEncoder functions that accept those flags as an
argument.
