BUG: 3084. Fixed multiple usability issues in ROI selection in Tractography Display module.
1. Changing Percentage Fibers Shown does not update display
2. Percentage Fibers Shown should update on mouse release not on drag
3. The ROI selection controls should be inactive until Fiber and ROI are selected to prompt users to select
4. Better name for ROI nodes needed
5. Tube slices do not show up on the newly created Fibers

ENH: Added versioning of SetupForDevelopment script

Recording the version of the development environment will help notify the
developer to re-run the SetupForDevelopment script. This can be done when there
are changes made to the environment setup scripts or to the client-side hooks.

The SetupForDevelopment script records the version of the developer setup in the
Git config file. This version is tested against the version specified in the
SetupForDevelopment script using the pre-commit hook.

This means, if there is a change in the developer setup (hooks, etc.), the
version number in the SetupForDevelopment script should be incremented to
notify other developers that they should update their setup.

BUG: #3040 build DCMTK as shared libraries

This avoids issues where dcmtk code is statically linked into more
than one shared library, meaning that some static initialization
and destructor code is being invoked more than once.  See the bug
report for details.

BUG: Observe scene after being populated

If a node is added into the scene while it is being populated
(updateScene() calls populateScene()), the added node might be added in
the wrong location and it might trigger modified event which confuse
the model.
Such added node can happen if a qMRMLNodeComboBox does not accept "None",
so it selects the first valid node as soon as it is added into the model
(by populateScene), selecting that node could trigger a node addition into
the scene (if someone observe the currentNodeChanged signal of the combobox).
