-------------------

Changed PETSc matrix format in NewMatrix which gives about
a factor 50 speed-up in the assembly. For assembly
FFC+PETSc is now the fastest combination in the benchmark
in src/demo/form/main.cpp :

DOLFIN + DOLFIN: 9.590000
DOLFIN + OPTIM:  0.570000
DOLFIN + FFC:    0.570000
PETSc  + FFC:    0.520000

Added rhs assembly to NewFEM, in addition to other updates
of NewVector, NewMatrix, and NewFEM, to prepare for new
structure based on FFC and PETSc.
