Enforce proper graphql query syntax

[ashfurrow]

eslint-plugin-relay does this here: https://github.com/relayjs/eslint-plugin-relay/blob/master/src/rule-graphql-syntax.js

The rule appears to do the following:

• prohibit ${...} substitutions in graphql-tagged strings.
• require GraphQL operations to be named.
• make sure that graphql.parse works on the query.
