Don't talk about other editors

So apparently there's now also Animatron, whose [first blog post][1] was
in April 2013 and claimed it'd been under development for "over a year";
even if it'd be under development for a whole 2 years, they couldn't
have started earlier April 2011, whereas [our first commit][2] was in
Sept 2010 (in fact, [our last commit before these hotfixes][3] was in
Jan 2011), so I'm not wrong about us being the *first* online editor,
but whatever.

There's also bly.sk, which appears to be defunct (they're website is
(c) 2011, and the last post on their Facebook wall is 2012).

As far as I can tell we're still the only open source JS animation tool
(although there's CSS3 animation creator: Mixeek), but whatever.
