/*
This is the source code for the lobby_connect.exe program.
If you want to build it, just dl the steam sdk and link it to the steam api dll
Then to execute it just use my emu dll instead of the steam sdk dll.
If you make any improvements and want to share them post your code in the thread and if it improves it I'll use it.
You can also use this code to add this functionality to your launchers.
Note if you use my steam emu dll: When I build my lobby_connect.exe I static link it to a build of my emu that has reading from disk disabled.
This means that it's a good idea for you to use local_save.txt so that your launcher doesn't conflict with running
games by having the same steam user id. There must also be no steam_appid.txt or else you will only see games with that appid.
