Added support for subnets to intel-framework.
The intel-framework now supports the new indicator type Intel::SUBNET. As subnets are matched against seen addresses, the field matched was introduced to indicate which indicator types caused the hit. A testcase for subents was added and the old ones have been updated accordingly.
