[Paraview] Ensight filename numbers patch

[Olesen, Mark]

I finally found out the root of my problem and have attached a
corresponding patch.

Problem: the VTK EnSight reader had complete garbage when expanding
wildcard names (eg, "scalar per element: k  data/********/k").

Cause: the reader assumed that the filename numbers occur on a single
line and immediately follow the "filename numbers:" introducer and did
not check the sscanf() return value. This can result in very incorrect
values for the filenameNum and/or useless animation values.

Example of a correct syntax (according to ens_checker) that triggers the
problem:

TIME
time set:        1
number of steps: 72
filename numbers:
 40           80           120          160          200          240
 280          320          360          400          440          480
 520          560          600          640          680          720
...
