Support object-like key names

[kljensen]

I have a key name for a resource that looks like the following:

aws_route53_record.module_ec2_webserver["www_656_mba"]_the_dns_record

That's because I'm using for_each over an object in my terraform configuration. I'd like to fix the nameParser regexp to handle this case. I can add some tests too. But, I don't have many examples of valid key names "in the wild". I'm hoping people see this issue and can tell me some valid key names and I'll fix the nameParser to recognize them all.
