EventEarlyNotification timestamp bugfix and other changes (#84)

This PR fixes EventEarlyNotification timestamp not displaying correctly
and also has some other changes:
- Add xmldocs for `/settingslist`'s `page` option in
SettingsCommandGroup.cs
- Add option description for `index` for `/delreminder`
- Some corrections of grammatical errors in Messages.tt-ru.resx
- Fix `ArgumentOutOfRangeException` in `/settingslist` that appears if
the user uses a negative integer in `page`
