[BUG] Setup.exe does not work properly with high contrast colour scheme.

[Tim O'Callaghan <timo at dspsrv dot com>]

Setup does not play well with any of the windows desktop high contrast
color schemes. It is usable with "High Contrast #2", but utterly
unusable with "High Contrast Black".

Essentially the background for the text used to describe a package or
package group is fixed to 'White' rather than the system default. So
if you use a windows color scheme like "High Contrast Black", which is
a black background with white foreground text, you cannot see the
displayed text.

This is easily verified by running setup.exe under a high contrast
scheme, or switching schemes while setup.exe is in the package
selection menu.
