Import yet some more small fixes to libteken sources:
- 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. Spotted by: Paul B. Mahol <onemda@gmail.com>
