Shift+Ins - paste buffer
Shift+PrintScr - prev. screen

Add FreeBSD ID tags while I'm here, since people often copy an exiting
keyboard map and then edit that and try to commit it.

- Fix errors in some keymap files.

- The numpad * key should always generate *.
- The numpad - is fkey52 and should not generate a control code (0x1f).
- The numpad 5 is fkey54, not fkey61.
- The numpad 6 is fkey55 and should not generate a control code (0x1e).

NOTE: us.unix.kbd and us.emacs.kbd are very much different from the
other keymaps, thus, I didn't touch them.

The control code ^_ (0x1f) should really be called `us' rather than `ns'.

- Correct inconsistencies among keymaps.
- define CTL-ALT-ESC as `debug' key in all keymaps. (FAQ mentions this
key sequence but not all keymaps had it!)
- define CTL-SPACE as NUL in all keymaps.
- define CTL-ALT-SPACE as `suspend' key in all but Russiun keymaps.
- Fix Japanese keymaps. Some CTL- keystrokes were wrong.
- Remove accent (dead) key definitions from spanish.iso.kbd,
fr.iso.kbd and icelandic.iso.kbd. Create spanish.iso.acc.kbd,
fr.iso.acc.kbd and icelandic.iso.acc.kbd with accent key definitions
instead.
- Update INDEX.keymaps and Makefile.

Polish fonts and keymap.
