Added support for markdown in gfm() function
Created by: ameily
- It appears that gfm() never called the base markdown() function
- Commit messages and other items would only render the reference fields of gfm ** Emojis, user names, issues, commit ID, etc
- The name Gitlab Flavored Markdown implies that base markdown syntax is supported
- Adding the call to markdown() renders all GFM text correctly
