DateTime.UtcNow is from at least 30 up to even 117 times faster than DateTime.Now. We have many places in which we compare our date to previous one we set ourselves - in all those places we can (and should) use UtcNow instead of Now.
Local DateTime is still around in some places, those that are user-specific, such as when logging messages.
This is another great idea I thought about - ArchiHandler already receives all packets from Steam Network, so why bother checking if steam client is still alive if we can make use of the time last message arrived, and send request only when needed.
Extra points for performance benefits for accounts receiving lots of packets, so mainly primary ones with lots of friends/groups
Time to enforce some common file layout, as general mess started to annoying me. Sorry in advance for people using custom forks and having merge conflicts, this will help everybody in long-run
Previously we had rather half-blind mechanism of trying to play given games, expecting a disconnect, and reconnecting in AccountPlayingDelay minutes. Now instead we have proper event-based handling - ASF listens on each PlayingSessionState event and updates availability of farming accordingly, not only resuming farming immediately after it's possible, but also limiting number of reconnects and other issues which could be caused by previous approach.
I bet this can be even further improved to not receive LoggedInElsewhere and disconnect error when user starts playing a game, but that's misc compared to gigantic improvement in this commit
