Emoji and precompiling

[bodrovis]

I've created a brand new app with Rails 4.1.1. Firstly I got this problem: #550 (comment) but then I've tried to use some smiles in my test posts and started to get these errors:

Asset filtered out and will not be served: add `Rails.application.config.assets.precompile += %w( emoji/smile.png )` to `config/initializers/assets.rb` and restart your server

I believe that asking users to specify all the smiles for precompilation is not an option.

@bodrovis: is this still an issue?

I believe this won't be an issue when the 596 will be merged. I will have to test this however because I hadn't used Forem for a while.

Which part of #596? It is quite a large PR and I'm considering closing it and asking it to be split out into multiple PRs. Is it the emoji config inside Forem::Engine which needs doing for this?
