Log Message:
Update to 4.15:
* New hacks, `wormhole', `mismunch', `noof', and
  `pacman'.
* `phosphor' and `apple2' include vt100 emulators now:
  this means you can do "phosphor -program top", or
  can use either program as an xterm replacement:
  "apple2 -text -fast -program 'xemacs -nw'".
* `analogtv' (and related) fill the screen better.
* The '-gradient' option works in `atlantis' now.
* Minor updates to `blinkbox', `queens', `endgame',
  `glmatrix', `mirrorblob', `blocktube', and `molecule'.
* Integrated SuSE's "external passwd helper" support.
* Marginally better /tmp handling in various programs.
* Updated config defaults for xplanet 1.0.3.
* Portability fixes.
