[kbd] dvorak-programmer keymap.

My friends and me use "Programmer Dvorak" for a long time.

We can find it in X, but can not find it in kbd. It's a nightmare with
using qwerty or standard dvorak on a new machine.

So we wrote this,  would you mind to add it to kbd-project ? (i386/dvorak)

> Long time ago, I requested this. But you said the old version was very difficult to maintain and make changes. So I rewrote it.

Hope you can merge it in. Thanks. If don't, please tell me. ;)

The following is the keymap.
