Fixes a bug that was preventing Rails app startup

[disbelief]

Error was:

'method_missing': undefined method `assets' for #<Rails::Engine::Configuration:0x007fca48b60e58> (NoMethodError)
from handlebars_assets/lib/handlebars_assets/engine.rb:5:in 'block in <class:Engine>'

Seems to be a simple logic error here:

class Engine < ::Rails::Engine
    initializer "handlebars_assets.assets.register", :group => :all do |app|
      config.assets.configure do |sprockets_env|
      # ...
    end
end

Note that config does not exist here, however app.config does. Changing to that fixes the problem.

Surprised no one else has encountered this as it completely prevented my Rails app from starting.

@disbelief I think this might be true only for a specific version of rails ... hmm; what version of rails is this on ?

[disbelief]

@AlexRiedler ah yeah maybe this is true. It was happening to me on Rails 3.2

[AlexRiedler]

I think this change is harmless; I will do some testing tomorrow and have a patch fix tomorrow

Bump.

Can we please get this merged?

changing config.assets to app.config.assets is compatible with Rails 3 and Rails 4.

This is how other gems are doing it: https://github.com/railsware/smt_rails/commit/13c526af2b1b6acc7f41131226f536be8e65a49e

Oh I think change log should also updated too.
