The change was required for utterances to take advantage of the more granular permissions scheme offered by the GitHub App model. With the current OAuth App, utterances must request the public_repo scope just to read/write issues and comments. A lot of extra permissions we don't need come along with this scope and users have raised issues (see #23). With the new app model, utterances will only have read/write permissions on issues & comments in repos where the utterances app is installed.
Inlines README.md during the build.
Previously the html for the README.md file was loaded via a GitHub API call and inserted into the utteranc.es home page at run-time. This was a lazy hack, now that we're using parcel+posthtml it can be integrated in the build very easily.
