Write date to logs

[H0L0theBard]

Suggestion from #560

This PR adds dates to logs in the same format which the file name uses.

Closes #560

Replaced my northstar.dll with the provided .dll, played a bit, worked as expected and didn't encounter any issues

Code looks good, date format uses the long variant 👍

[Alystrasz]

Code looks good, testing shows date now appears in log files.

This only affects the log files (and not things like the in-game console) right?

[H0L0theBard]

This only shows in logs.

One trade-off is that this change will increase log size due to preventing more characters for each line. Personally I think this trade-off is worth it.
It might also break existing log parsers but that's not our problem.

If there's no opposition to this PR I'll merge it within the next few hours or so.

Would it be worth restricting this to only dedicated servers? Listen servers and clients shouldn't really be having the game open for multiple days at a time

Users can sometimes send their logs as a message.txt in the Northstar discord so having the date in the log can help in verifying if it is actually a recent log.

That's basically the only idea I have in why we'd have it for clients and listen servers. We also recently reduced the spam of some lines in a couple of PRs so I don't personally see any issues with adding a little bit extra onto each line.

as an alternative if this isn't "enough" reason, I can have spectre check message.txt files, check if they're northstar logs, and ask for an actual log upload

imo it makes less sense to do it this way (spectre way), and instead just keep date in client logs, but it's an alternative

Fair enough, good enough for me

Imma count that whole discussion as primarily in favour of having date in logs on both server and client and merge as is ^^
