Updated your makefile to run with the local npm installed browserify and a global installation of inkscape

Thanks for noticing!

• As for locally-installed browserify: for some reason I only committed 8b387ec locally in 2016 and didn't push… 😰 That should fix that.

• As for Inkscape, why do you suggest this change?:

   shapesVis.png : out/shapesVis.svg
   	# Rasterise the SVG file to a PNG
  -	inkscape $< --export-png=$@ --export-area-drawing
  +	inkscape $(shell pwd)/$< --export-png=$(shell pwd)/$@ --export-area-drawing
  +
   	# Flip it vertically (because the y-coordinates we get out of potrace
   	# increase in the other direction)
   	mogrify -flip $@

  Surely pwd is always the root directory of the project if make is run?

  Unless I am mistaken, the change would have no effect.
