 * @class Ext.air.Clipboard
 * @singleton
 * Allows you to manipulate the native system clipboard and handle various formats.
 * This class is essentially a passthrough to air.Clipboard.generalClipboard at this
 * time, but may get more Ext-like functions in the future.
 *
 * The Clipboard has different types which it can hold:
 * CONSTANT - value
 * air.ClipboardFormats.TEXT_FORMAT - air:text
 * air.ClipboardFormats.HTML_FORMAT - air:html
 * air.ClipboardFormats.RICH_TEXT_FORMAT - air:rtf
 * air.ClipboardFormats.URL_FORMAT - air:url
 * air.ClipboardFormats.FILE_LIST_FORMAT - air:file list
 * air.ClipboardFormats.BITMAP_FORMAT - air:bitmap
