Simplified the theme info section of the footer. Mentioning every single
contributor looked to bloaded whereas leaving one out would not have been fair.
This is why i decided not to point to an authors website directly, but to
the theme itself on http://get-simple.info/extend/ where proper credit is given
to all parties involved. If anyone disagrees with my changes feel free to
contact me and I am sure, we will find a compromise :-)
