[feature request] auto-configure IMGKit gem

[MathieuDerelle]

like you do for pdfkit, wicked_pdf, and wisepdf, maybe you could do it for https://github.com/csquared/IMGKit

IMGKit.configure do |config|
  config.wkhtmltoimage = WKHTMLTOPDF_PATH
end

Hi @MathieuDerelle - the IMGKit gem requires the wkhtmltoimage binary.
Unfortunately right now we only provide wkhtmltopdf

I don't mind if you fork this repo and make a separate gem for wkhtmltoimage 😄
