Add perl modules needed to build "slic3r"
Add perl modules needed to build "slic3r"

Slic3r is a tool to convert a digital 3D model into printing
instructions for your 3D printer. I have some build/run issues with it
so add it later.

These perl modules are added:
  AlienWxWidgets
  BoostGeometryUtils
  constant-defer
  ExtUtilsCppGuess
  ExtUtilsTypemapsDefault
  ExtUtilsXSpp
  GrowlGNTP
  MathLibm
  MathClipper
  MathConvexHullMonotoneChain
  MathGeometryVoronoi
  MathPlanePath
  ModuleBuildWithXSpp
  NetDBus
  Spiffy
  TestBase
  Wx

A couple of old modules were no longer available on CPAN so I bumped
them:
  DataUUID
  ExtUtilsMakeMaker
  ExtUtilsManifest
  version
  VersionRequirements

XMLTwig fails in the test phase (it is missing a dependencies), so the
test is skipped. (How did it pass the test before?)
