Just an initial portion for now fixing incorrect text and preventing future incorrect text. Eventually, I'd like to fix everything still listed under "ignoredWords" in cspell.json.
- add prewarnings
- update history table (migration)
- I added a check in the announce controller for the completed event sent by client. During that event I added `$history->immune = ($user->group->is_immune == 1) ? 1 : 0; ` which is pretty much saying is the user in a immune group upon download completion. This will solve people in immune groups that download but dont meet 7 days seedtime but then get demoted and banned. As we wont issue warnings for history records marked as immune.
