Add license to policy-engine files

Added license to various files.
Updated XACMLPolicyScanner to work even when license comment
is added to the Policy.xml file.
Moved DOCTYPE before license in html files.
Removed license from css files, as many are generated or
come from third-party software.
Removed license from other generated files.
