Easier way of accessing Dictionary values from services, components, non-pipelined MVC controllers

[jattwood]

Arising out of this discussion, https://our.umbraco.com/forum/using-umbraco-and-getting-started/110717-umbracohelpergetdictionaryvalue-invariant-to-variationcontext-culture#comment-346213 it seems to me that a "sanctioned" means of accessing dictionary values from non-pipelined classes is needed. Injecting Umbraco Helper seems like a lot of overhead just to get a dictionary value. I am probably missing something here but the documentation says nothing about retrieving dictionary values other than Umbraco helper inside a pipelined controller. There are many cases when you need to get dictionary values from inside a view component, API controller, traditional MVC controller, service class, etc. I know there is ILocalizationService but in the nomenclature of Umbraco, the word service usually implies a database hit. I ended up writing a Translation Service class that you can see at the end of the thread. Thoughts on this appreciated.
