Refactor code so that two L.Illustrate.Textbox instances are created: one during drawing, and one when the 'draw:created' event is fired (I realized that the second L.Illustrate.Textbox instance is created so that it can be returned to the user via the 'draw:created' event, and the user can add it to the map themselves - for example with drawnItems.addLayer(layer)).  Correct the size of the second L.Illustrate.Textbox instance and enable typing on focus.
