Rails 5 deprecation warnings

[gyng]

Rails 5.0.0.1 throws the warning when used with libsaml:

DEPRECATION WARNING: before_filter is deprecated and will be removed in Rails 5.1. Use before_action instead.

The warning is thrown inside controller_helper.rb. before_action is not available in Rails 3, which, according to the gemspec, is supported by libsaml.

Will libsaml up the Rails requirement to Rails 4? I updated activemodel and activesupport to >=4 and tests are still passing. While just annoying right now, it will break with Rails 5.1.

I think we can create a separate branch for < Rails 4.2 for however uses it. But I will upgrade the gemspec to require at least Rails 4.2 to stay inline with the Rails maintenance policy.
I will make a major release version for this change.

Separate branch is created an deprecation warnings have been removed. We will do some tests in our own applications to check for any issues before releasing
