 * Handle events of the "datebox" type.
 *
 * Valid events:
 *  - close : Close the control
 *  - open : Open the control
 *  - set : Change the date (p.value == date Object or date String)
 *  - doset : Populate the date
 *  - dooffset : Offset the date (p.value == amount, p.type == field)
 *  - dorefresh : Refresh the display
 *  - doclear : Clear the input
 *  - clear : Re-read the input?
 *  
 * @param  {object} e jQuery event
 * @param  {object} p DateBox event
 * @param {boolean} p.closeCancel No idea what this does.
 * @param {string} p.method Event method to run
 * @param {*} p.value Can be a date object, date string, or amount to offset date
 * @param {string} p.type Field to offset
