Update QPalette() documentation to not mention the application palette 

It's an implementation detail that the default constructed palette
happens to use the d-pointer of the application palette, and as a
result has the same colors as the application palette if requested.

The palette has an empty resolve mask, and hence all the colors in
the palette are undefined. Users should not rely on QPalette() to
represent the application palette when for example overriding a
parent palette.
