Sometimes, you just want your toast to bounce. You know?

I've added options to specify show/hide methods and easing, rather than just using fadeIn/fadeOut. For example:

        toastr.options = {
            positionClass: "toast-top-full-width",
            showMethod: 'slideDown',
            showEasing: 'easeOutBounce',
            showDuration: 'fast',
            hideMethod: 'slideUp',
            hideEasing: 'easeInBack',
            hideDuration: 'fast',
            newestOnTop: false
        }
