Support Multi-(multi-zome-)DNA Applets

[weswalla]

Given the generic applet webhapp bundle architecture:

We need the representation of an applet happ to sufficiently map resources to where they exists (path: dna/zome/entry). Since these dnas are bundled as a happ, we can reference them using their respective roleIds.

Such proposed changes would affect:

• applet config

the resource_def key in the object would change from a ConfigResourceDef[] to something more like:

{
    [roleName: string]: {
        [zomeName: string]: ConfigResourceDef
    }
}
