Fix Sending Chunks to Client - Fixes #1504

Browse Source 
Vanilla has some screwy logic that doesn't send a chunk until
it has been post processed. This is an issue as post processing
doesn't occur until all neighbor chunks have been loaded.

This can reduce view distance while generating terrain, but also
cause bugs where chunks are never sent to the client.

This fix always sends chunks to the client, and simply updates
the client anytime post processing is triggered with the new chunk data.
