Update logo.png to the new Varbase logo

Problem/Motivation

The project page and repository show the old Varbase logo, while the other Varbase projects use the new one.

Proposed resolution

Replace logo.png at the repository root on the 1.1.x branch with the new Varbase logo, the same file the other Varbase projects use.
