Breaking change: rename sync/wait fns and add wait as a synonym for sleep:

* wait is now a synonym for sleep (is more expressive from a music perspective for the operation)
* sync is now called cue - you ‘cue’ new actions musically - cue :bass!
* wait is now called sync - you sync the current thread to the future cue
monkey patch Integer#times into Float (after a to_i on self)
