Diff to previous 5065
Merging ripley diagonal storage + CUDA support into trunk.
Options file version has been incremented due to new options
'cuda' and 'nvccflags'.

Proof-of-concept 2:
matrix assembly on CPU as before, solving via cusp-based dia matrix on CPU
or GPU according to options.
CPU->GPU copy time is in the order of 1-2% of solver time,
solver speed-up is nice.
Unfortunately, no MPI support in cusp so this is just to confirm that
it makes sense to pursue further with custom solvers using thrust.
