* If all the conditions are met, generate an instance of the Diaspora Comment Virus

* Previously all comments from any Hubzilla source (including those who have not opted in to
* Diaspora federation), were required to locally generate a Diaspora comment signature.
* The only exception was wall-to-wall posts which have no local signing authority.
*
* Going forward, if we are asked to propagate the virus and it is not present (due to the post author
* not opting in to Diaspora federation); we will generate a "wall-to-wall" comment and not require
* a source signature. This allows hubs and communities to opt-out of Diaspora federation and not be
* forced to generate the comment virus regardless. This is necessary because Diaspora now requires
* the virus not just to provide a stored signature and Diaspora formatted text body, but must also
* include all XML fields presented by the Diaspora protocol when transmitting the comment, while
* maintaining their source order. This is fine for federated communities using UNO, but it makes
* no sense to require this low-level baggage in channels and communities that have chosen not to use
* the Diaspora protocol and services.

/* How Diaspora performs "like" signature checking:
- If an item has been sent by the like author to the top-level post owner to relay on
to the rest of the contacts on the top-level post, the top-level post owner should check
the author_signature, then create a parent_author_signature before relaying the like on
- If an item has been relayed on by the top-level post owner, the contacts who receive it
check only the parent_author_signature. Basically, they trust that the top-level post
owner has already verified the authenticity of anything he/she sends out
- In either case, the signature that get checked is the signature created by the person
who sent the salmon
