* two new types of aliens. only one rules.
* removed gfx_write in favor of gfx_putchar and gfx_putstr.
* added bonuses at alien death. they do nothing yet.
* seeker missiles. 'b' to test.
* weapon resolution is now 16*char. needs to be generalized.
* fixed the supernova bugs. center could collide with the tunnel, and
the last frame was badly displayed.
* lots of cleanups everywhere.
