Update require access rule to work with ESLint 4

[jleja]

BlockComment events are no longer being emitted in ESLint 4 (https://eslint.org/docs/user-guide/migrating-to-4.0.0#event-comments), and attempting to use this plugin in a project with ESLint 4 will not trigger this rule.

Changes include:

• Rewrite require-access-in-comments rule to use the same events as ESLint's valid-jsdoc rule
• Expand tests to cover new event types
• Add package-lock.json to repo
• Include same code changes as #57 to fix failing tests/prevent conflicts
• Add parserOptions to plugin's eslintrc file to allow us to use more modern code styles
• Remove plugins section from recommended config to prevent fatal error in ESLint 4 when it goes to validate config properties (https://eslint.org/docs/user-guide/migrating-to-4.0.0#-unrecognized-properties-in-config-files-now-cause-a-fatal-error):

  plugin:ember-suave/recommended "before all" hook:
  Error: Failed to load plugin ember-suave: Cannot find module 'eslint-plugin-ember-suave'
