Bug - ember-inflector throws when included more than once in an app/addon

[jenweber]

If someone yarn links ember-inflector, they can end up with two copies running. defineProperty used in deprecations will throw because the prototype is already defined:

TypeError: Cannot redefine property: pluralize

This can possibly be patched by passing { configurable: true } when defining the prototype:

Object.defineProperty(Ember.String, 'pluralize', { configurable: true });

There is a merged PR removing these deprecations, but it's unreleased and it's a major breaking change: #154 This change might be a possible patch version until the "real" fix goes out in a release.
