Can't run gem

[ivan-leschinsky]

1. I'm running this gem and inside lib/slack_mailer.rb there are some undefined constants:

ActionController::Base
ActionView::Base

And seems like you don't need ActionView to render erb template file.

require 'erb'
ERB.new(File.read("file.erb")).result(binding)

it will see instance variables from the class from binding is passed

2. In the file lib/slack_mailer/delivery_worker.rb you used sidekiq but I don't see it in the Gemfile or slack_mailer.gemspec.

@ivan-leschinsky we had write this gem only for Ruby on Rails don't for Ruby.
Sidekiq must be installed separately of this gem - https://github.com/appodeal/slack_mailer#dependencies

[ivan-leschinsky]

@wwwermishel but don't you think you should add these gems to the slack_mailer.gemspec as dependencies 😞? Like you do with slack_notifier gem.

@ivan-leschinsky i think you can open PR with this changes, if you have a time.
