New fileBrowserPrivate and fileHandler APIs added + plus magic needed to safely hand over access to local file system elements from content extension to 3rd party extension.

As agreed with aa@ and asargent@, this new API defines following event:

chrome.fileHandler.onExecute.addListener(function(id, file_entries) {
}

This event is invoked when user selects files in ChromeOS file browser.
 
The extension needs to register itself as file content hanlder with following manifest changes:
  ...
  "file_browser_actions": [
    {
      "id" : "ActionIdentifier",
      "default_title" : "Action title",
      "default_icon" : "icon.png",
      "file_filters" : [ "filesystem:*.jpeg", ... ]
    }
    ...
  ],
  ...
