Updated git submodules

Project: policy/engine master 4a4628d57bf3d11fda68e16f695139d512f75354

Fixed bug introduced by sql injeciton protection.

Added missing colon before the named parameters. Fixed a typo parameter
name. Fixed bad cast by setParameter.

This fixes issues encountered in the UI. Whenever a policy is moved,
renamed, or deleted it makes a db call and that db call fails on
setParameter method. This hibernate method is supposed to automatically
detect the type of the object for the named parameters but it fails with
type Long. It tries to convert to int and it fails. A check is now added
for type Long.
