Initially I wanted to make it configurable to choose either HTTPS (preferred), or HTTP, depending on user choice.
I strongly believed that it WAS possible without much headache, and solve many older Mono issues without any strong code drawbacks.
However, Volvo proved me wrong yet again, as it seems that using HTTP just like that for accepting a trade makes it impossible, and that's ONLY because we're using HTTP and not HTTPS, even if all other data, including referer, post and request, looks exactly the same.
It's quite sad that I must remove this option, but I literally discovered that switching this to true makes accepting trades impossible, and that is beyond the point I can accept, as user could switch this to true when he doesn't need it, and limit program functionality without even knowing that this is the cause.
Everybody using up-to-date Mono should have no issues using HTTPS, even legacy TLS 1.0, so hopefully this won't hurt that marginal percent of users that had this set to true in the past. It was mentioned in the wiki that this option might disappear later on, and this is the moment when it doesn't only should, but MUST, disappear... 😢
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
1. Make sure that every call to steamcommunity has active session
2. Move whole userspace logic for session handling to ArchiWebHandler (and Bot)
3. Implement session caching and TTL so we won't send IsLoggedIn() on each ArchiWebHandler call
4. Instead of restarting whole steam account, just refresh the session via ArchiWebHandler instead
