Callbacks missing

[martinp-ccs]

Hi, is there a plan to implement callbacks such as there were in the original CodeSeven library shown below (mainly looking for OnClick() event)

// Define a callback for when the toast is shown/hidden/clicked
toastr.options.onShown = function() { console.log('hello'); }
toastr.options.onHidden = function() { console.log('goodbye'); }
toastr.options.onclick = function() { console.log('clicked'); }
toastr.options.onCloseClick = function() { console.log('close button clicked'); }
