Follow-up of Slicer/VTK@3e45140d5 (BUG: use alpha to calculate RGBA lighting)
introduced through 57b8434 (BUG: Update VTK to fix RGBA volume rendering).

It removes the use of regex leading to segfault in binary compiled using gcc 7.3.1 and introduces an ivar called lightingComponent set based on the value of "independentComponents"

See #7281

List of VTK changes:

$ git shortlog 3e45140d5..97965bba9 --no-merges
