Add context to README about transition from Mozilla to jsfiddle

[gene1wood]

Last time I looked, togetherjs lived with us in the https://github.com/mozilla organization . It's since been transferred to the https://github.com/jsfiddle organization. Looking in issues and code I don't see any information as to when or why this was done.

Do add some background on the project (about how it came out of Mozilla Labs, was put on a shelf in 2014 and then at some point in the last couple years was transferred to jsfiddle)

See this issue for a bit of information.

Thanks @da-Jester !

It looks like jsfiddle forked it here on Feb 28, 2020, but after that there appears to be only one commit a few days later and then nothing since?

@oskarkrawczyk Can you add any details here?

• Was that fork turned into a redirect somehow ( github.com/mozilla/togetherjs redirects to github.com/jsfiddle/togetherjs )
• The domain name, togetherjs.com, appears to still belong to us (Mozilla). It resolves to CloudFront which points to web content that refers to https://github.com/mozilla/togetherjs . Should this web content be updated?
• If I PR an addition to the README that gives a few sentences of background for folks confused by the site being hosted by/owned by Mozilla and the GitHub repo being owned by jsfiddle, would that be welcome?
• Does jsfiddle indeed own it now? I ask because after the transfer it looks like no work has been done on it (code, issues etc)
• Is there any desire to point hub.togetherjs.com or hub.togetherjs.mozillalabs.com to the glitch.me hub?

I'm a Mozillian and big fan of togetherjs, just want to make it successful.
