Please unblock simplesamlphp/1.6.3-1 (security)

["Thijs Kinkhorst" <thijs@debian.org>]

Hi,

simplesamlphp/1.6.3-1 has been uploaded in which the only code change is
an XSS security fix. Other changes are confined to documentation so it
didn't seem opportune to extract the fix only.


Thanks,
Thijs
