Add cask for NetBean

pkgutil-based uninstall is somewhat greedy, applying to packages
matching org.netbeans.*|glassfish-*. NetBeans bundles a GlassFish
instance inside its install directory. GlassFish proper doesn't install
using Mac OS X installer at all, so hopefully no GlassFish paths will be
deleted accidentally based on the receipts. Uninstall also has to
delete /Applications/NetBeans since not all files are in the receipts
database thanks to some postflight unpacking.
