Twitter sized logo for JBug Newcastle

As a follow up on DESIGN-164, we would need an improved icon as avatar on Twitter.

I added whitespace and then cropped one of the existing logos to use here: https://twitter.com/JBugNcl
As you can see it results in a lot of space and very small characters. Would be great to have something with the two words on separate lines and more readable to better fit in this shape.
