* Moved panel controller to chromeos directory

* Include BrowserExtender to regular build to remove CHROMEOS ifdefs in BrowserView
 * moved browser_extender.h to chrome/browser/views/frame, and BrowserExtender methods
   to chrome/browser/views/frame/browser_extender.cc.
 * Added StandardExtender (standard_extender.cc), which is empty now. I'm going to add MainMenu support to win,
   which will be added vua StandardExtender with a command line flag.
 * factory method "Create" is now defined in standard_extender.cc and chromeos/chromeos_browser_extenders.cc.
   toolkit_views=1 uses chromeos_browser_extenders.cc and other build uses standard_extender
