Export/Import of settings

[rockyd]

Feature request the ability to export settings from one version of Gargoyle, so they can be imported into another version. This idea came to mind as I was copying settings from one box in Gargoyle to the same box in another version of Gargoyle. for me static DHCP assigments and port ward would be the main things, but if possible the idea could be used for the all of the Gargoyle settings.
