Fix a 64-bit issue in TrilinosWrappers::SparseMatrix::local_range().

This tripped up all of the Trilinos sparse matrix iterators in 64 bit

 <ol>
+  <li> Fixed: TrilinosWrappers::SparseMatrix::local_range() erroneously
+  threw an exception in 64-bit mode. This is now fixed.

   <li> New: The GridOut::write_gnuplot() function produced output
   for 1d meshes embedded in higher dimensional spaces that was
   invalid in that the lines showing individual cells were connected.
