Create a "blacklist" and "whitelist" mode
antibody created issue #790 on 2011-10-28T15:11:00Z:
Create two server modes for incoming requests:
Whitelist mode - only accept POST requests from servers that were manually entered (with their hashkey). Servers not matching the hashkey or servers that are marked as inactive will not be allowed to submit new data.
Blacklist mode - accept POST requests from everyone, provided that the servers are marked active (change to inactive to prevent submissions).
