Extracted most non-Rails logic into the icons gem (#97)

* Extracted most non-Rails logic into the icons gem

Rails Icons has been, as the name implies, Rails only. But there are
many other great frameworks and Ruby apps that can benefit from the
Rails Icons' core: pulling SVG icons from their GitHub repos, easily
sync them and offer a class to render them, with various attributes as
SVG.

Find the [icons gem](https://github.com/rails-designer/icons) here.

* Updated Appraisal gemfiles
