COMP: vtkPichonFastMarching - Replace finite() with isfinite()

finite() is not universally in the c standard.
isfinite is support in all c compilers since
c99.

As of Mac 10.9 under clang, finite() issues a
warning that it will be deprecated and that the
standards conforming isfinite() should be used.

COMP: C++11 require space between string constants

C++11 now allows for custom type specifiers so needs
a space when two string constants are to be concatenated.

COMP: Fix configuration of Slicer against system python

When building against system python, the pydicom module won't be
installed at configure/build time.

A Slicer runtime test could be added to check if expected python module
are available.

Thanks to "Dominique Belhachemi <domibel@debian.org>" for reporting the
problem.

BUG: avoid spurious warnings from DataProbe during startup

Make sure the frame member of the widget is set before
setting up observers to avoid a situation where the processEvents
is called before setup is complete.  This avoids some spurious
warning messages during startup.
