* NOTES: 

+ Added setab/setaf quotes from the XTerm terminfo.
    + Proposed a workaround for bright colours on any terminal.
  * src/caca.c:
    + 16 colour support for ncurses and conio.
  * src/graphics.c:
    + Ported to 16 colour support.
    + Added a missing <stdio.h> for BUFSIZ.
    + Disabled vsnprintf under DOS (only vsprintf exists).
  * examples/:
    + Don't abort if the caca.txt sprite was not found.
    + Ported to 16 colour support.
