Preliminary Linux unicode support?

Maybe this horribly breaks something? It seems too easy...

Of course you need the ncursesw headers to compile it... err, "sudo apt-get install libncursesw5-dev" or whatever.

And it's only for linux console.

I changed the main menu items to unicode codepoints (for example "\u611b" == 愛) to test it out.
