Add Dream World Pokémon art.

Add Dream World Pokémon art.

All Pokémon are present except for Keldeo, Meloetta, and Genesect.
All forms are present except for Zen Darmanitan.
No female art except for Frillish and Jellicent.

The art was taken from pokemon-gl.com in SWF form, converted to SVG with
pyswf, and minified with a custom script.

Although the minification does provide a modest space savings of about
1MB (5%), its real purpose was to make the art less of a pain to work
with in Inkscape (by removing unneeded <use> tags).
