Fixed finalization bug in vtkTimeStamp.

Finalization of vtkObjectFactory was calling vtkTimeStamp::Modified
after the static atomic int was destroyed. Used Schwarz Idiom
to fix the initialization dependencies.

I also had to change ProcessShader.cxx to not include vtkObject.h
as it does not link against vtkCommonCore. All it needed was to
include system headers to get iostream.

Prefer to overflow rather than die when wrapping lines

Some of our documentation cannot fit into 76 characters, when that is
the case prefer overflowing over the default (to die). This allows
conversion of the headers to continue despite a few Doxygen comments
that don't wrap perfectly.
