CP-7941: Update SDK within XenCenter 6.5.

CA-121385 Allow creation of VLAN 0 in XenCenter. This applies to the New Network Wizard and the Network Properties.

- The VLAN can be set to 0 only for Creedence or greater hosts on the vSwitch backend.
- When VLAN 0 is selected, an info is shown next to the control, saying "VLAN 0 will receive all traffic not on any other VLAN"
- Also fixed an error on New Network Wizard, where the "VLAN in use" message was still visible when changing the NIC.

CA-136288 Restore application settings after installing a new version of XenCenter

When running XenCenter after a new installation, and the program's hash has changed (e.g. by .NET 4.0 upgrade), the previous settings are not automatically restored because they cannot be found (they are there, but in different folder).
We need to try and locate a config file from a previous installation, and if found, update the settings from there.
