[Joyride] Enable Joyride to bypass callbacks on close event

# foundation.joyride.js
* Add a flag to bypass callbacks on close event

## Description
This feature introduces `abort_on_close`'s flag to bypass all `*_callback` called on the `close` event.

This is useful when you have to run *Joyride* across many different pages, **I.E.** we're on the first page, the tour has started, you don't want to follow it and then close it by `x`, after this, it doesn't have to fire any callbacks.
