gnuplot1d gives error on plot of facevariable

[fipymigrate]

When plotting a facevariable, one obtains the error:

Traceback (most recent call last):

In the patch in attachment, the exception determines the use of cell or face centers. Probably there is a way in fipy to query what type of variable it is, if so, fix can be better ...

I now encountered the same problem with 2D gnuplot viewing.
New patch faceplot_improved.patch uses the class to determine what to do, and works for 1D and 2D Facevariable plots.

Fixed with r4537.
