By default support only NTLMv1 like other browsers. However, make it possible

for users to manually enable the usage of NTLMv2 authentication by adding a
"EnableNTLMv2Auth=true" flag to either one of the following to configuration files:

$KDEHOME/share/config/kioslaverc OR
$KDEHOME/share/config/kio_httprc

Note this setting like every other ioslave setting can be set on a per site
basis by adding the parameter to a host specific section instead of the global
one. For example,

[foo.bar]
EnableNTLMv2Auth=true
