Replace epsfig with graphicx

The graphicx package allows for file specification without a hardcoded
extension.  This provides more freedom in chosing how to prepare images
in *.eps and *.pdf formats.

Moreover, epsfig is considered mostly obsolete in the TeX community and
graphicx is the "current 'preferred' solution" to embed figures.
