qemu/ui/cocoa.m
Peter Maydell 1879f241e6 ui/cocoa.m: Update documentation file and pathname 
We want to stop generating the old qemu-doc.html; first we
must update places that refer to it so they instead go to
our top level index.html documentation landing page.
The Cocoa UI has a menu option to bring up the documentation;
make it point to the new top level index.html instead.
