"about" dialog is formatted, with "GoldenCheetah is Licenced under
the GNU General Public Licence." and "Source code can be obtained
from http://goldencheetah.org/" run together in a single paragraph
because the way the line is broken after "Source".
The attached patch splits the two sentences into two separate
paragraphs, and centers the entire dialog text.
While this is subjective, I think it looks a lot better.
