fix rails 5 deprecations

[xprazak2]

This continues where #671 left off, I tried to get in touch with the original author but I did not hear back from him. I added conditional checks to keep backward compatibility.

@rafaelfranca Any chance of getting this in? We can fork, but this seems really useful to those of us who've yet to upgrade to Turbolinks 5.

[mmoll]

could there be a 2.5.4 release on rubygems?

[jhubert]

@rafaelfranca Woohoo! Thank you. 💟

[rafaelfranca]

Yes of course. I'll release it tomorrow

[mmoll]

@rafaelfranca I know I'm annoying, but: any news here?

[mmoll]

anybody?

[rafaelfranca]

I still didn't had time to release it, but I'll work on it soon. Meanwhile you can always point to github using bundler (this is one of the best features that bundler has)

[rafaelfranca]

Oh. It was easier than I thought. It 2.5.4 is released now

[mmoll]

@rafaelfranca Thanks a bunch! Because of the way we package our software for nightly RPM/DEB builds it's not easily possible to use git repos in bundler for production builds...
