Update Programm, to update installed Reactos

Hi!

It would be nice, to see an update programm or something like that, to update
ReactOS to the newest Version, without reinstalling it. For example, compile
ReactOS under ReactOS and this programm then installs the new compiled version.
Like the windows update. So for example you dont have to burn a cd-rom and
loose your data every time you want to update reactos, when you have installed
it directly on the disk in a separate partition.
