Fixes #1173 - Exclude the JDK tools jar to prevent IDE import issues in non-OSX environments. Also do some opportunistic formatting refactoring
#1174 - Add placeholders for all source folders to ease IDE project management between branches
Merge branch 'BroadleafCommerce-3.0.x' into BroadleafCommerce-3.1.x
Remove placeholders no longer needed from #1174
