7458: Using the replies collection

NodeBB has elected to partially follow FEP 7458 for maintenance of the replies collection.

Our implementation

A replies route is available for every local post in NodeBB. This route resolves to an OrderedCollection containing a chronologically-ordered list of Note objects who have identified as being inReplyTo the requested post.

In NodeBB, they are considered "direct replies".

Please note that the replies route is always present even if there are no direct replies to the post.

Partial Implementation

FEP 7458 lays out the foundational elements related to cross-checking an incoming object for presence in the inReplyTo.replies collection.

At this time NodeBB does not satisfy this requirement. All incoming objects are parsed, assuming they satisfy the internal check for an existing relation.
