remove bin directory and clean up dependencies for 1.0

[Eric Wyne]

For a 1.0 release @gramps/gramps needs to remove all /bin features and clean up dependencies accordingly (in favor of @gramps/gramps-cli.

From what I see a production @gramps/gramps should only have:

dependencies: {
  graphql-tools,
  lodash.merge
},
peerDependencies: {
  graphql
}

Closed in favor of gramps-graphql/gramps#20
