Copy in Firefox, Chrome and Safari

// We can't copy stuff in clipboard in Chrome, Safari and Firefox (Opera)
// Maybe one day this tickets will be resolved – 
// https://bugzilla.mozilla.org/show_bug.cgi?id=407983 
// https://bugs.webkit.org/show_bug.cgi?id=17645
// But if they will, we still can only copy text to clipboard only during clipboard events
// We might get around this, it's not a production code, just...

var clipboard = function() {};

// If we have firebug installed
if ( console.notifyFirebug ) {
    clipboard = function( text ) {
      console.notifyFirebug( [ text ], "copy", "firebugExecuteCommand" );
    }
}

// It also gives us event in Safari and Chrome for keyup in console
console.__defineSetter__( "_commandLineAPI", function( api ) {
    clipboard = api.copy;
