v0.4.0

Changelog

• Migrate to using ember-template-lint. All existing rules are supported and were migrated to ember-template-lint as the underlying linting engine. ember-cli-template-lint is now an ember-cli specific wrapper around ember-template-lint.
• Add deprecate-each-syntax rule. Prevents usage of {{#each foo}} (context shifting each) and {{#each foo in bar}}.
• Add self-closing-void-elements rule. Prevents closing void elements (<input /> will error in favor of <input>). See here for a list.
