[Feature Request] wire_frame 'source' parameter

[diegohce]

The main idea is that we can use a 'source' parameter to set an url for the wire_frame macro but, as opposed to 'initial', source will not be fetched once the frame is rendered. So we can have an empty initial state for the frames.

With this, we can use events to trigger those requests.

Hmm. The target parameter was meant for updating a frame during mutation. Is this not sufficient? Is there a specific use-case you are trying to cover?
