Publish as official Gem?

[deliberist]

I admit this is arguably a non-essential request, but since this repo seems to be the original source code for the project, can you publish "official" gems?

Based on the README, the normal way to install the plugin is to include it as a sub-module to my repo. I could disassociate the sub-module from Git, and just include the flat files. I could also just suck it up and deal with sub-modules. But I think it would make this project a bit more developer friendly if one could just run gem install jekyll-rst or put gem "jekyll-rst" in their Gemfile.
