baseurl missing for local emoji

[Sora1248]

My blog isn't located at the root of my webspace but in a subdirectory. So I've set the baseurl accordingly in my _config.yml.
After installing your plugin and trying to use emoji from a local directory instead of including them from GitHub I've noticed that the plugin correctly found the image files in the local directory but generated the wrong URL for the img-tags: The baseurl-part of the URL was missing.
Adding the baseurl to emoji-images-path didn't work either as the look up of the local image files failed that way.

As a start here's my quick&dirty patch:

diff --git a/_plugins/emoji_for_jekyll.rb b/_plugins/emoji_for_jekyll.rb
index 39eb05d..1d0f04b 100644
--- a/_plugins/emoji_for_jekyll.rb
+++ b/_plugins/emoji_for_jekyll.rb
@@ -38,7 +38,7 @@ module EmojiForJekyll
         Dir.foreach(images_dir) do |image_filename|
           if /^(?<tag>.*)\.(?:svg|png|jpg|jpeg|gif)/ =~ image_filename
             @master_whitelist << tag
-            @images_path[tag] = File.join("/", images_path, image_filename)
+            @images_path[tag] = File.join("/", site.config["baseurl"], images_path, image_filename)
           end
         end

This solved the problem for me but obviously needs some additional checking if baseurl exists at all.

Sorry for not just providing a merge request with a final solution, but I don't really know Ruby and just don't want to deliver a botched C++-style solution. 😉

@Sora1248 This looks good. Can you please turn this into a merge request? I guess the only change needed here is to do something like

baseurl = site.config["baseurl"] || ""

and pass it into File.join.
