Andreas Lauser fa2f2cf9ed TPFA: change the way how gradients are calculated
before this, gradients had the direction of the face between two
finite volumes, now they exhibit the direction of the two
FV-centers.

For axis-aligned grids the result is identical for interior faces, but
it is different for boundary faces or if faces are not
axis-aligned. This patch fixes the SPE9 troubles with anisotropic
permeabilities on tilted grids...
