[Gmsh] Two modification patches to gmsh-2.0.7

[OSHIMA Takuya]

Hi Christophe,

So many thanks for including the patches into the Gmsh source!

And although the 20070521 nightly source seems to work basically fine,
I'd like to make further modifications as attached
(StreamLines.fix.patch) if possible, so that

* multi-step plot correctly works for a view that starts from time
  other than zero,
* "Time display mode" -> "Value" works for the streamline view.

Maybe I should have included the fixes from the first post of the
patch...

Cheers,
Takuya
