Localize Maven

This CL introduces a new development plugin that downloads all
dependencies into the given repository. This will allow us to
build data binding in build servers w/o internet connection.

By default, it is setup to disable public repositories to avoid
adding a new dependency w/o running the script.
Public repositories can be added by running -PaddRemoteRepos=true.
There is also a convenience script to fetch dependencies.
