Use Clang as the compiler for the Mac platform. Changed all Mac to use clang/clang++ as the default C and CXX compilers if not provided by the user. Still use gfortran as the default fortran compiler since Apple does not provide any fortran compiler. Tested: passed all three macs OS, snow leapord (fred), lion (duck) and mountain lion (wren). Also passed test using Apple gcc, Gnu gcc, Intel as the C compilers and all corresponding CXX compilers fits in. Did not run h5committest or other non-mac platform since this change affect Apple platforms only.
