Implement name fetching capabilities for Webkit and Quicktime plugins
Adds support for new PluginAPI message (MEDIA_EVENT_NAME_CHANGED) that updates the "title" of the media. In WebKit plugin this is the contents of the <title> tag. In The QuickTime plugin it is the "display name" from the movie meta data
