storageGen.lua broke some time ago, since Milo stores non-used nodes in
the config with an "ignore" type, so if Milo was ever launched before
storageGen.lua, then storageGen.lua wouldn't work. Also, storageGen.lua
used to be stored in packages/milo/apps but it seems some shell or
package changes have made that no longer in the shell path, so I moved
storageGen.lua out of packages/milo/apps.
