BUG: load() now returns the loaded node

This behavior is consistent with the other plugins.

COMP:  DoubleConvert needs to be included

In order to build BRAINSTools, the External_DoubleConvert.cmake needs
to be built prior to building the BRAINSTools.

COMP: Fix double-convert external project so that it works as intended

1) The previous version was working because the double-conversion project
was exporting its build tree in the cmake package registry.

See http://www.cmake.org/cmake/help/v2.8.10/cmake.html#command:export

Since the package was exported, the find_package(double-conversion ..) within
BRAINSTools was working. Line like the following weren't not used at all:

  list(APPEND ${CMAKE_PROJECT_NAME}_SUPERBUILD_EP_VARS ${extProjName}_DIR:PATH)

2) Remove dependency to DCMTK. See https://github.com/BRAINSia/BRAINSTools/issues/5

ENH: Clean code and add command line option "--temporary-path"

Remove unused headers

Remove tempDirectory initially added with r11985,
qSlicerCoreApplication::temporaryPath  (added with r15424) should be used
instead.

Calling slicer with both --testing and --temporary-path options returns
the directory associated with testing.

$ ./Slicer --temporary-path
/tmp/Slicer

$ ./Slicer --testing --temporary-path
/tmp/Slicer-tmp

Example:

  slicer.util.saveScene('/tmp/currentscene.mrb') # Save scene as MRB file

  slicer.util.saveScene('/tmp/currentscene') # Save scene as directory
