Add symlinks in ./src/node_modules for backwards compatibility.

See "Note for plugin authors" section in Changelog.

Some packages that are in use by plugins got a symlink in
./src/node_modules so that they still work after updating Etherpad. In
the future don't require('etherpad_ep-lite/node_modules/dependency')
anymore, but change this to require('dependency') and add the dependency
to your plugin's package.json
