Updated things to the latest release of Substance LaF which has been taken under the Insubstance project. Current version is 7.2.1 released about 7 months ago. The project is currenrtly looking for a new maintainer, so whatever that will mean. I know we are possibly looking to stip Substance out... but perhaps an updated version will fix the previous issues? And some of it's LaF's do look good ;-)
1) Apply the patch.
2) Copy "substance.jar" to "~/spark/codebase/build/lib/dist/"
PS: You have to compile spark from source to get the updated Substance to work. Simply copying "substance.jar" over to your Spark installation will not do it.
