Updates needed for QUnit core v1.15.0

[JamesMGreene]

Some unofficial public API methods are being removed in QUnit core v1.15.0. This plugin needs to be updated to account for such changes.

The undocumented but formerly public QUnit methods that have been removed in v1.15.0 are:

• QUnit.id
• QUnit.addEvent
• QUnit.addClass
• QUnit.hasClass
• QUnit.removeClass

It would be nice to generate a new release with this fix.

@FagnerMartinsBrack: Good call, sorry about that.

@Krinkle @scottgonzalez: I've got ~5 little commits ready to push out as the next version (updates to devDependencies' versions, updated AUTHORS/mailmap, actual version bump, etc.). Could one of you kindly grant me maintainer rights to https://www.npmjs.org/package/qunit-composite? NPM username is "jamesmgreene". Thanks!

@JamesMGreene done

[JamesMGreene]

Thanks, @scottgonzalez.

@FagnerMartinsBrack: Now published as v1.0.2. Thanks for your patience and the reminder.

[FagnerMartinsBrack]

Yeah thanks, I was using the master branch code.
Nevertheless it is always good to release ASAP such a breaking change like this one.

Cheers.
