ArchiSteamFarm V0.9 (pre3)

• [!] Added new feature called "ASF 2FA", which enhances ASF by an ability to work as mobile authenticator for Steam two-factor authentication. Please check https://github.com/JustArchi/ArchiSteamFarm/wiki/Escrow for more information
• Added new config property, UseAsfAsMobileAuthenticator which enables ASF 2FA for given account. Default is false, and should not be changed without understanding the logic behind it
• ASF no longer requires entering 2FA code on each login for traditional 2FA-protected accounts
• Made ASF more friendly regarding working with primary accounts. Check out #25 for more details
• Added priority for 2FA reconnect requests, so they're not limited by the request limiter and do not expire too fast
• If SteamMasterClanID is defined, now apart from joining chat of given group, bot also joins the group itself (if it's public)
• Misc WebBrowser optimizations
• Other misc optimizations / cleanups

Notice: This pre-release has been released to test new ASF 2FA implementation. If you have any feedback, check out #24
