updated ant logos

[Martin Schlömer <ma...@ruhr-uni-bochum.de>]

Hi,

i changed the text to 'built by' and i included one version without the
text.

These logos are not supposed to be final. It just the way i think the
logo should look like.
You can change the font styles if you please. Or the colors. Or the
text.
The font is Century Gothic and should be freely available.
Or the size. The reason i supplied the logo so huge is, you don't need
to pixel edit it at that size.
The only part i don't want to be changed is my ant head. The drawing,
that is. ;)


Martin.
