Add evaluation of .bit.arpa to dev docs
Also add a news post about the document
@hlandau and/or @midnightmagic : any chance you could review this?
Looks good to me. I can think of no other objections. As long as we persist in the overriding nature of personal lookups against a local namecoin node, I think it was nice of them to suggest a .bit.arpa and while not a true TLD, it does provide a significant reputational boost, which IMO won't hamper us from continuing to lobby for a true TLD (and then either a move or an addition or repurposing of .bit.arpa later on for some unforeseen but better purpose.)
This is on hold for a while; will come back to this later. Please do not merge without talking to me.
If it's WIP, maybe mark as draft?
