ScriptDownloader is not defined + patch

[Lekensteyn]

When choosing "View User Script source" from a context menu (on .user.js URL's) I get a "ScriptDownload is not defined".
The following change in content/browser.js fixed it for me:

GM_BrowserUI.viewContextItemClicked = function() {
 var uri = GM_BrowserUI.getUserScriptLinkUnderPointer();

  //ScriptDownload was undefined, using GM_ScriptDownload instead
  this.scriptDownloader_ = new GM_ScriptDownloader(window, uri, this.bundle);
  this.scriptDownloader_.startViewScript();
};
