Optimisations
- Settings cache, gives about 8x speedup to accessing properties, especially important in large syncs but also when reading options while rendering PR cells
- Simplified settings & app delegate singletons into global variables, since their lifetime matches the app’s.  It makes the code clearer, also makes method dispatches to them about 10% faster too
- Added optional logging to console in OSX
Username displayed in comment/mention notifications
Stronger repo names, saner option groups
- PR subtitle code cleanup
- Repo names will be slightly stronger and positioned at the start of the PR subtitle
- iOS cell height estimation, and appearance improvements
- Moved options relate to repo name display and filtering into the display section, slightly clarified their names
To test PR section issue
Fix for settings regression
- User ID is now stored as a number, not a string, meaning that no comments or PRs were being identified as “mine” anymore.
