Support the `exclude` property

[ivogabe]

See microsoft/TypeScript#3188

Thanks for this but there are two issues with your implementation (as per the original referenced TypeScript pull request):

• the property name is exclude and not excludes
• it does not use glob patterns (unless I'm mistaken, your implementation requires values such as node_modules/** which are not supported by TypeScript's implementation)

You're right about that, I've fixed it.
