Bundler needs `require`; should document that in README or change file

[jeremywadsack]

When I tried to use this gem, I got this error:

NoMethodError:
  undefined method `before_render' for ReportsController:Class
  Did you mean?  before_filter

This is happening because bundler isn't autoloading the gem's files because the file name doesn't match the gem name. I resolved this by changing my gem line as follows:

gem "rails5_before_render", require: "before_render"

A quick solution to this would be to update the README.md with the above change.

Alternately, changing lib/before_render.rb to lib/rails5_before_render would resolve that problem too. That might cause a breaking change (for those who have already required the current file); you could keep lib/before_render.rb and have one of those two files require the other.
