Title: Can be used without rails

I'm using this gem as a dependency to other gem (https://github.com/tomgi/git_stats) without requiring rails. It doesn't work since https://github.com/tomgi/lazy_high_charts/commit/6e82d67034037bb4b3c72e2f4de9221eb2731df7#L5L5
Restored check for `defined?(::Rails::Railtie)`
