Importing can fail for resources that use locally defined properties

[joepio]

If you create a new property (localhost/myprop) and use that in a resource, and then create an export of that server, and then try to import the json-ad file... It might fail if it encounters the resource that uses that prop before it encounters the property itself.

This might seems like a very big if, but the problem has already been encountered and is quite logical, as many users will create properties and import back-ups.

How to deal with this?

• Change the ordering of the resources, make sure the properties always are at the top. this can (for now) be done manually by opening the .json-ad file and changing the order.
• When get_property is run, try the imported file first (seems quite complicated)

I've changes the export to first do the properties. It works, but I'd still prefer the import function had a way of dealing with this.
