+ 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.
