Consider licensing issues when opening Boilerplate up to more customers

[yorinasub17]

From #111

[Older versions licensed as MIT] might become an issue if we ever open boilerplate up to other customers, as legally all those commits are licensed as MIT.
It would be a bit of a pain to retroactively update the LICENSE file, especially with all the release tags. I think the best way to handle this would be to fork boilerplate and start the history a new when we are ready to start sharing it with more people.
