Fixes a bug with shared children, view next lines for more details.
When you run cap deploy:setup it should create directories for all shared children
at shared/child_dir, not shared/path/to/child_dir.  Additionally, when you deploy
capistrano should symlink all shared children to the correct current dir - for
example, deploy should symlink shared/child_dir to current/path/to/child_dir.
