[krbdev.mit.edu #5609] NIM GUI picture does not track tray icon

[Jeffrey Altman via RT]

I object to this patch.  Watermarks are becoming a standard UI component
of applications.  The watermark is shadowed and is not a indication of
credential status.

If MIT wishes to disable the watermark display, it should make the
display conditional upon a registry setting.  Use khc_read_int32() to
read a DWORD value from the registry.

I would suggest using the value "HideWatermarks" DWORD in the key
"CredWindow".  MIT should set this value to non-zero to trigger the
hiding of the watermarks.

Be sure to update the appropriate schema (.csv file) when you add
registry parameters.
