Echo JS 0.11.0

I think it'd be really complex to include the whole @requires tree manually since it's actually quite long (for instance, toggleClass depends on addClass() which depends on eacharg(), which depends on args(), which depends on each()).

Maybe splitting it into a "core" and "plugins" would be a better idea but then we'd also need to separate the plugins by type, as .adjacent() is used by .after(), .before(), .append() and .prepend() but by nothing else so it's not really a core plugin but also a dependency. This also has its problems.

So I think in total is not really worth it.

okay it's a shame. I guess I just copy paste what I need then.
