Additional API methods for Alert

[VizuaaLOG]

Over the next few versions I think it would great to expand the API methods available, allowing certain settings to be changed at run time, rather than needing to recreate the component. The below are ideas for the alert popup, any other ideas please just comment!

• hide() - Hides the alert
• show() - Shows the alert
• toggle() - Toggles the visibility of the alert
• type(new_type: string) - Changes the alert's type, adjusting the CSS classes applied
• title(new_title: string) - Changes the title of the alert
• body(new_body: string) - Changes the body of the alert
• confirmLabel(new_label: string) - Changes the label for the confirm button
• confirmClose(new_state: boolean) - Sets if the confirm button will close the alert
• confirmDestroy(new_state: boolean) - Sets if the confirm button will destroy the alert
• cancelLabel(new_label: string) - Changes the label for the cancel button
• cancelClose(new_state: boolean) - Sets if the cancel button will close the alert
• cancelDestroy(new_state: boolean) - Sets if the cancel button will destroy the alert
• isVisible(): boolean - Returns true if the alert is visible, false otherwise
• trigger(event_name: string) - This will trigger the provided event on the alert instance. Note: This wouldn't be restricted to documented events, so could be used for handling custom events

It's likely the open / close events will also be renamed to show / hide respectively. It's more descriptive of what's actually happening, an alert is shown not opened.

The methods above will also be able to get the relevant value by not providing the parameters.
