+ Error checking in ee_init().
    + Pre-generate the empty line for ee_clear().
  * libee/sprite.c:
    + Better error checking in ee_sprite_load().

+ Added ee_color_names[] containing our 16 color names.
  * libee/ee.c:
    + Extended our color set to the full 16 instead of 10.
    + Precalculate ncurses attributes.
  * libee/graphics.c:
    + Clip color value in ee_set_color().
    + Clip characters in ee_putchar().
    + Partially clip characters in ee_putstr(), overflows aren't checked yet.
  * libee/ee_internals.h:
    + New file to share extern variables within libee.

  * test/demo.c:
    + Added a simple demo_color() to output all colors.
    + Replaced four ee_draw_line() with ee_draw_thin_box().
    + Replaced x1, y1, x2 etc. with xa, ya, xb etc. because <math.h> already
      defines y1.
    + Randomized colours from 0 to 15 instead of 1 to 10.

  * src/Makefiles.am:
    + Added -lm to the ttyvaders linking flags because of the intro.

  * README BUGS TODO:
    + Updated.

+ Added a note about dos cross-compilation.
  * configure.ac:
    + Added a check for ScreenUpdate in <pc.h>.
  * libee/graphics.c libee/ee.c:
    + Improved the conio port thanks to ScreenUpdate().

+ Moved ee_putstr() and ee_putchar() in here.
  * libee/ee.h:
    + Got rid of ee_goto().
    + Moved <slang.h> or <curses.h> into libee.
  * Replaced ee_goto()/ee_putstr() pairs with ee_putstr().
  * Ditto for ee_putchar().

+ got rid of DELAY.
  * test/demo.c:
    + Minor animation effect.

+ Moved ee_get_key() here.
  * libee/math.c:
    + Moved r00t() here and renamed it to ee_sqrt().
    + Moved GET_RAND() here and renamed it to ee_rand().
  * src/math.c:
    + Removed this deprecated file.

+ First file in libee, from src/graphics.c.
    + Disable cursor upon initialisation.
    + Added delay code for constant framerate.
  * src/common.h:
    + Minor compilation fix for latest ncurses.

* lots of sanity checks in collide.c.
  * moved usleep() to graphics.c.
  * added random key generator in the dummy driver.
  * cosmetic changes in the energy bars.

* fixed an overflow in the tunnel update code.
  * fragbomb is now 'f', not 'd'.
  * added a missing call to init_bonus().

* added GPL headers to source files.

* 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.

the nuke is still ugly, almost no collision detection. Nice demo :)
