Implemented VLAN-to-VLAN routing support for SDN-IP.

SDN-IP can now support peering and routing between hosts that are connected
on VLANs.

Changes include:
 * Updated NetworkConfigReader app to read (optional) VLAN configuration
 * Updated VlanId to support the 'VLAN present' value - in a match this means
   that a VLAN tag must be present, but it can contain any value.
 * Updated SDN-IP to set destination VLAN tag values if appropriate
 * Updated FlowModBuilder and FlowEntryBuilder to support 'VLAN present' value
 * Slew of test updates.
