Why does it take the debian-7.3.0-i386-lxde-CD-1.iso installer so long to install inside a VirtualBox VM?

You could reconfigure the debconf package - see dpkg-reconfigure(8). 
However, there are some questions that you probably should see when 
upgrading, for example when a config file that ships in a package has been 
modified since installation and you need to decide whether to install the 
new config file or stick with the old one.  Having had to do this very 
thing today, sometime the answer was one and sometimes the answer was the 
other, and mostly it involved a bit of both (choosing one answer but 
adding some content from the other).  The ability to view a diff betwee 
the files is a big help in these situations.
