ENH: Begin post-4.1.0 development

STYLE: Fix spell mistake in additional launcher settings target name.

Additonal -> Additional

COMP: Ensure that SlicerBlockAdditionalLauncherSettings can be included mutliple times

In case UseSlicer.cmake file is included more than once, the target
'ConfigureAdditionalLauncherSettings' was defined more than once which
was causing the following cmake error:

// -----------
CMake Error at /home/jchris/Projects/Slicer4/Extensions/CMake/SlicerBlockAdditionalLauncherSettings.cmake:49 (add_custom_target):
  add_custom_target cannot create target
  "ConfigureAdditionalLauncherSettings" because another target with the same
  name already exists.  The existing target is a custom target created in
  source directory "/home/jchris/Projects/SkullStripper".  See documentation
  for policy CMP0002 for more details.
// -----------


Let's also note that we envision multiple extension built within one
project, only one target is required since the launcher settings are
currently module/extension agnostic.

STYLE: Within SlicerConfig, change signature of help macro to be consistent with CMake style

CMake build-in function, macro and command are all specified using lower
case letter.

Adding one "_" is also sufficient to indicate the function or macro
is not specifically for re-used outside the code of this module. It also
means that the api and implementation of this function is expected to change.

BUG: Make sure 'slicer_setting_variable_message' works with long variable name

The helper macros used within "UseSlicer.cmake" have been factored out
into UseSlicerMacros.cmake to allow their testing.
