JSON linting in the code editor

[AndrewBastin]

This PR intends to add the ability for the Ace Code Editor to provide linting for JSON files in Postwoman.

You can try out the linter through any editor instance that specifies JSON as the language (so basically the GraphQL variable editor and the POST request content editor (when content type is set to application/json)).

Hey @AndrewBastin,
Something went wrong with the build.

TravisCI finished with status errored, which means the build failed because of something unrelated to the tests, such as a problem with a dependency or the build process itself.

@AndrewBastin @liyasthomas I've introduced a new prop to the Ace Editor component (<Editor />). You can specify a lint prop like <Editor :lint="false" /> and it will disable linting for that editor. The reason for this was because the response box on the GraphQL page is supplied with :lang="'json'". However when the runQuery function is run .. it updates the response box to regular text Loading... (which isn't json), thus showing a linting error.

While the runQuery function should return json, we shouldn't run any linting on it anyways as the data is coming from an external data source. (Plus; they can't edit the content in the response box)

This lint prop may come in handy for other editor boxes in the future, so I think it's a decent addition. 💯
