Update the LAPACK quick reference guides

The ATLAS user API is defined in the quick reference guides under AtlasBase/TexDoc. Right now, the supported LAPACK API is small enough to fit both C and F77 interfaces on one card (single 2-sided landscape page), but eventually it will be split in two, as with the BLAS quick reference cards. Either use the Makefile to do it, or remember to manually throw the -tlandscape flag to dvips, and the -paper a4r flag to xdvi.
