Windows installer on Windows XP cannot display messages, when the
installer database is encoded in UTF-8 and support for CTL languages
is not installed. This patch is a workaround, it disables the 'Remove'
button in Control Panel's Add or Remove Programs applet, so the user
has to choose 'Change', and has to uninstall LibreOffice with the
Wizard, which does not exhibit the problem.
Initially this bug was not expected, when we changed the enconding
from legacy codepages to UTF-8 - I would say irreversibly.
Then the severity of the bug was underestimated, because usually
uninstallation needs no user interaction, so it does not matter,
if the text is unreadable. However, in some circumstances
uninstallation needs to reboot the computer, and the user needs
to understand the question, whether to reboot now or later.
