Installer updates

[ViciouZ]

I think it would be useful if the NSIS script was updated with an option to download the HR4 pack while installing. I know other installer systems using NSIS do stuff like this quite regularly, I just thought it might help by showing the new players that the game can look nice, while not forcing those with limited space/bandwidth to grab the files they might not want.

Could the NSIS script for the installer be put in the CVS?

I regenerate the installer script for each build using the HM NIS Edit wizard (since manually adding each new file to the install/uninstall would be a pain in the butt).  There's probably a better way to do it, but whenever I start working on it, I spend a lot more time than just manually generating it each time and making some tweaks.
