Import yet some more small fixes to libteken sources:

Browse Source 
- Implement NP (ASCII 12, Form Feed). When used with cons25, it should
  clear the screen and place the cursor at the top of the screen. When
  used with xterm, it should just simulate a newline.

- When we want to use xterm emulation, make teken_demo set TERM to
  xterm.
