Make rails dependency an optional

[JelF]

Idea:

• Exception_notifier somehow could be configured to use appropriate mailer. As far as i see, there is no generalized way to provide secitions views to a generic mailer, but i don't sure exception_notifier not locked to ActionMailer descendants, so there probably could be a way to configure all ActionMailers to respec our views. If not, views should be moved to appropriate generators of frameworks
• Load rails-related code via special file lamian/rails.rb, so they could be easily loaded, but only if rails requested
• Probably add hanami/rb / sinatra.rb files for thoose frameworks

@fiscal-cliff offered some help, would you do all this work for me?

@fiscal-cliff, I can do #8 to simplify this task for you

I managed to sort out this issue
First of all, the notifier itself has rails as a dependency. The only way to evade this requirement is to use simple_email_exception_notifier which we use already. The notifier provides plain text formatter which is not compatible with :email notifier. So rendering request_log section inside the notifier turned out to be way harder than I expected. I've patched the notifier as follows

module SimpleNotifierPatch
  def compose_message(exception, env, options)
    SimpleEmailExceptionNotifier::Message.compose do |m|
      m.print_summary(exception)
      m.print_section('Backtrace', exception.backtrace)

      m.print_section('Request log', Lamian.logger.dump.split("\n")) # <<< !!!

      unless env.empty?
        m.print_request(Rack::Request.new(env)) if defined?(Rack::Request)
        m.print_section('Environment', filter_env(env))
      end

      m.print_section('Data', extract_data(env, options))
    end
  end
end

ExceptionNotifier::SimpleEmailNotifier.prepend(SimpleNotifierPatch)

I would advice you to look up alternatives for ExceptionNotifier since this solution looks extremely dirty.

ExceptionNotifier-related stuff could be moved to rails-only section in this case, same as it's views and rails engine.
Also, consider use Lamian.dump instead of Lamian.logger.dump, because Lamian.logger is part of private api and this comands do same stuff

OK, that's just kinda demo, proof of concept

I will not add non-rails support untill i need it in production. However, pull requests are welcome

Core functionality is rails-independent, same is middleware itself. Rails engine should be required in "lamian/rails" and readme should be updated. Exception notifier API is not required in non-rails for oblivious reasons (exception_notifier bound to rails), so i suggest to add API for Raven
