BUG: Don't install already-installed dependencies

When considering an extension's dependencies, don't prompt about (or
attempt to (re)install) dependencies that are already installed.

Issue #2912

STYLE: Add debugging to Extension Wizard

Add additional debugging information to the Extension Wizard when
creating a compare URL for a pull request to (hopefully) help diagnose
failures. Add a (hidden) --dryRun option which will skip actually
creating the pull request during --contribute.

BUG: Update SubjectHierarchyGenericSelfTestTest to support VTK6. Fixes #3720

In both VTK 5 and 6 cases, the pipeline is connected and the
explicit call to "Update()" is not required.

BUG: Update CTK - Fix "No such slot" warning and optimize ctkVTKConnection

* Fixes #3361: Fix "No such slot" warning and optimize ctkVTKConnection

* Fixes #3719: py_SubjectHierarchyGenericSelfTest passes but it output warning about slot disconnection

* Improve performance of ctkVTKConnection creation/removal

* Add Qt5 support to CTK

* Thanks to Eric Larson. ctkAbstractView now provides a method allowing to
set multisampling.

* Since ctkErrorLogModel has been moved from CTKCore to CTKWidget (because
QStandardItemModel belongs to QtGUI), similarly the error log model has
been moved from qSlicerCoreApplication to qSlicerApplication.
