Done using a few regular expressions & find & replace.
Fixes many -Wextra-semi warnings.

A simple implementation of private dependencies, with some of the most
obvious private dependencies moved over. This should be used for all
dependencies that are not exposed in the public API of the classes in
the module.

The target_link_libraries call defaults to private due to the way CMake
implements the link logic. The private dependency logic can help reduce
link line and include directory length for private links where the
dependency's API is not exposed in the module. Also added code to ensure
include directories are not duplicated for modules in the build tree.

Just added 'static' in front of many private functions.

I exposed several data members through getters in order
to be able to develop custom readers in Python. Also added a
hint to export GetUpdateExtent() to Python. In this particular
case, I am combining the XML reader and the MPIImageReader
to read a structured grid. The XML reads the meta data, the
MPIImageReader reads the appended data using MPI/IO.

Some of the module dependencies were somewhat weird, like
IOImage depending on IOGeometry and Rendering depending on
XML which contains all XML reader. Fixed the depency problems
by creating XMLParser and Movie modules and moving some
classes to them. I also moved many classes to RenderingCore
because they were only needed there.
One other minor change is to change vtkProperty to use
vtkImageReader2Factor such that it didn't explicitely depend
on bunch of reader. This will allow us to add/remove readers
to IOImage more easily.
