Rails 5 Support

[koenpunt]

With Rails 5 around the corner, I've removed deprecated functions, and made use of new functionality like Module#prepend.

EDIT

Oh well, it seems I overlooked some other PR's. (namely #267 #248)

Thanks, I was looking for this!

For those who want to use it, it can be used by adding following line to your gemfile;

gem "bootstrap_form", github: "fetch/rails-bootstrap-forms", branch: "rails-5"

@koenpunt Since #267 has been merged, can we close this PR? If there is more needed to support Rails 5, let me know and I'll do my best to review and merge it in. Thanks!

[koenpunt]

No, your branch was sufficient, thanks!

Although, if the test/dummy application gets updated to rails 5, my updated specs could come in handy

@koenpunt OK, can you make a note of that in issue #273? Thanks!

Turns out I was too quick with saying all was fine, because I didn't update my Gemfile yet, and it was still using a GitHub source.

When I use the bundled gem again, my tests produce a lot of errors, although I'm not sure what's causing them exactly, so will have to investigate.
