[IAEP] Set GNU GPL in monospace font

[Ryan Cunningham]

Are any of you convinced to set the GNU GPL in a monospace font in the 'About My Computer' control panel? If so, here's a patch for it (at the bottom).

The GNU GPL text file (v2.0) looks quite bad in a proportional font; but someone over at your GitHub repositories said that proportional fonts are better for dyslexic people.

Here, I import an additional standard PyGTK class, "Pango" (from the module "gi.repository"), to handle font switching.
