Support for ruby-2.4

[thomst]

The README declares ruby support for

Ruby 2.0.0 - 2.3.x

We use hourglass in version 1.1.1 with ruby 2.4.6-p354 for quiet a while and it is working fine.
Did you consider to officially support ruby 2.4 ?

Hi @thomst,
I am happy to read that it works fine for you.
It seems we planned to skip Ruby 2.4 and jump to Ruby 2.5 / 2.6 directly.
Right now this gives us build errors, I hope someone will investigate them soon.

Hi @arBmind.
Thanks for the feedback. Yes, it makes totally sense to skip 2.4. Unfortunately we stick to ruby-2.4 because of compatibility-issues of other plugins. I also remember that we once tried to update hourglass to 1.1.2 and had some minor issues. But I can't say if it was because of the ruby-version. Nevertheless thanks for the plugin. It is a great support for our company.
