Suggestion: allow to register listener on multiple elements at the same time #89
Description
Extend the API to support arrays when setting up keylisteners:
Old style:
new window.keypress.Listener(document.getElementByID('editor'));
// or with JQuery
new window.keypress.Listener($('#editor)[0]);
New Style (doesn't really change):
new window.keypress.Listener(document.getElementByClass('editable'));
This would even make JQuery integration more idiot proof (which I could have used ;-) ):
new window.keypress.Listener($('#editor));
