Installer: Use a simpler way to uncheck the console font option by default

Just make that component part of no types. In the same run change
documentation and code a bit to reflect the new idea that components that
should be installed by default in a fresh installation must have the
"default" type assigned.

Installer: Do not install any additional icons by default

This is in line with

    http://msdn.microsoft.com/en-us/library/windows/desktop/aa511450.aspx

saying

"Don't abuse the desktop - keep users in control. If your target users
are likely to use your program frequently, provide an option during setup
to put a shortcut on the desktop, unselected by default."
