Remove jquery from defaults

[gzoritchak]

As jquery is deprecated in kotlin/JS, its use should be an opt-in decision.

Hm..and what about users who already uses JQuery as a default library? :)

[gzoritchak]

I agree it's a breaking change but:

1. the workaround is very easy to set up.
2. who is using jquery today? ;-)
3. imposing the load of jquery to everybody is quite weird.

One of the initial idea of Kotlin was to be able to make it evolving. We shouldn't keep at runtime libraries deprecated since two major versions.

=) I'm using! For instance, in plain canvas example. Probably I might be drop the jquery in 1.19.0 or 1.20.0...I'll think
