Added onTouchStart handler to listeners

[sliterok]

Doing my research i found that library works on easypz.io for mobile devices only because of polyfills. Not the case with my app so nothing was listening for touchstart event.

svg element event listeners on my website:

svg element event listeners on easypz.io

None of touch actions were working for me. Adding touchstart handler to listeners list has fixed the issue.

If someone need temporarily fix it'll look like:

easypz = new EasyPZ(...)
easypz.removeHostListeners()
easypz.listeners.touchstart = easypz.onTouchStart.bind(easypz)
easypz.setupHostListeners()

My bad! Thank you for this, looks good! Works again now.
