Updated Japanese Translation

I found some strings are not translatable for now...
Here's the list:
Drawer ("Website", "XDA Thread","Follow Me on Twitter", "Follow Me on Google+", "Become a Fan")
Header ("Welcome", "Kernel Control", "Sound Control", "Touch Screen", "Help Center")
CPU Control ("Cores Online:")
Power Management ("Sorry, your kernel does not seem to support the Intelli Plug hotplug driver", "Sorry, your kernel does not seem to support the Intelli Plug eco mode")
