Update p5-Lingua-Stem to 0.84.

Changes from previous:
----------------------
0.84 2010.04.29 - Documentation fixes to the En stemmer and removal
                  of the accidentally included lib/Lingua/test.pl file
                  Thanks goes to Aaron Naiman for bringing the
                  documentation error to my attention and to
                  Alexandr Ciornii and 'kmx' for the pointing out
                  the problem with the test.pl file.

0.83 2007.06.23 - Disabled Italian locale tests due to changes
                  in behavior of Lingua::Stem::It causing
                  test breakage

0.82 2006.07.23 - Added 'stem_in_place' to base package.
                  Tweaks to documentation and build tests.
Add the latest development version of graphics/libcaca.

libcaca is a graphics library that outputs text instead of pixels,
so that it can work on older video cards or text terminals. It is
not unlike the famous AAlib library, with the following improvements:

 * Unicode support
 * 2048 available colours (some devices can only handle 16)
 * dithering of colour images
 * advanced text canvas operations (blitting, rotations)

Libcaca works in a text terminal (and should thus work on all Unix
systems including Mac OS X) using the S-Lang or ncurses libraries.
It also works natively on DOS and Windows.
Add libcaca.
