Spell Checker

[jalextowle]

Comments (and code names) frequently contain typos. These typos can be caught in code review, but this is an inconsistent and time consuming way to catch the issues.

The best way of solving this problem would be to enable spell checking for comments and identifiers using an automated tool (similar to a linter). If ignoring the feedback is sufficiently easy and easy to see, then this could even be a good addition to CI.
