COMP: Make sure Update command is disabled using CMake < 2.8.9

While commit r20834 allowed Slicer to be configured using CMake 2.8.9, it
also prevented the UPDATE_COMMAND from being disabled using version < 2.8.9.

This commit revert it and fix the issue by re setting LOG_UPDATE 1

ENH: multiple improvements

Major changes:

* importer no longer supports importing from DICOM: instead, DICOM module
  should be used for this purpose (via MultiVolumePlugin)
* charting has been fixed to use MV attributes instead of MV node for setting labels
* bug has been fixed in importer that caused crash on exit and added "ghost"
  MV node
* importing procedure has been updated, leading to reduce load time for MVs
  imported from non-DICOM data

COMP: include ctkDICOMDatbase.h to avoid us of incomplete class

Although slicer can compile without this header included, there
are warnings about use of an incomplete class and this could
cause problems for Qt and PythonQt wrapping.

Unfortunately, with this header included there are multiply
defined symbols between dcmtk's osconfig.h and pyconfig.h
that will need to be sorted out.

BUG: VolumeRendering was broken with doing ditor split and merge

Volume Rendering display nodes have the particularity to reference
displayable nodes. This is because the Bg/Fg display node needs to
reference 2 volumes at a time.
When a volume node is copied(Editor split and merge), it copies the
reference of the display nodes which make them to be used by 2 displayable
nodes at the same time. Volume Rendering display nodes don't support it.
And it seems unlikely that any display node will ever totally support it.

Closes #2135
