Render code voice in commit subject (supporting backticks)

[wesleymccloy]

I use backticks in my commit messages very frequently, and these are formatted in GitHub. It would be awesome if Fork did the same for the commit subject in the All Commits view.

e.g.:

abc1234 fixed issue where `utils.h` was incorrectly imported
abc1234 moved model files to `app/models/`
abc1234 added `README.md`

Would be formatted like so in the commits list:

• fixed issue where utils.h was incorrectly imported
• moved model files to app/models/
• added README.md
