wc3 splash screen

[Ann and Jason Edmeades]

I believe this fix to be correct. It certainly makes the warcraft3
splash screen appear (Without it, since realizepalette returns a value,
windows messages get sent to a thread which is not listening to
messages, causing a deadlock). Other functions in palatte seem to handle
the virtual palatte correctly, and I have seen no regressions caused by
this patch.

Changelog

With >256 colours, there is no need to realize a palatte, so skip it and
return that no palette entries had to change
