Several changes

- `cache.json` file was renamed to `.cache.json`
- `Patch.fetchTimeout` was increased up to 5 seconds from 3 seconds
- fixed *possible* issue with `Locales.default()` method:
  before, if you've been passing there a language to set as default,
  it wasn't returning properly
- added notification when all the patch repos are not available
