Fix EGS launch on Windows

[VirxEC]

This new login trick operates similar to RLBot v4, where the auth is gotten from the game's launch logs, except the game path is also read.

Tested on my machine, works fast & reliably.

This does not work correctly for me. The match launches, but I do not get logged in. My profile appears as "Player 1" and I get stuck in the main menu when I exit the match.

I think I spot the issue. Let me tinker a bit.

Here is the issue. We are currently reading from the log too quickly, so the info in there is from the last session. Auth password in that session may not be valid for the current session. It also means another copy of the ideal args gets inserted every time you use RLBot to open RL without opening it normally in between.

An easy fix is to read the game path from the logs but the auth args from the process.

Pushed a fix. I am now realizing that 43f8795 might have been intended to solve the same issue. Well, this new fix doesn't have to wait, so that's nice--Assuming RL has been launched at least once before.

Is this good to go now? LGTM
