Antibot - create a logo

I designed a logo for Antibot before this issue was opened. As Antibot wasn't on the list of projects under Project Browser, I submitted it directly to the Antibot project. It is in use by the project, though not yet in the repository.

Here's a preview of the logo.

Reviewed and the logo looks good to be used in Project Browser

Added SVG image with .txt extension.

Assigned credit and marked as fixed.

Automatically closed - issue fixed for 2 weeks with no activity.
