Readme instructions incorrect for Linux (Steam ver)

[sugozu]

Doing everything as the readme says always results in a crash with Steam version (it tries to run the game through Wine or something, even though the game can run without using Proton), which is easily fixable by having the Terraria bash file be modified to run the TerraCustom file instead, like tModLoader does, and then starting Terraria through Steam.

#!/bin/bash

# Move to script's directory
cd "`dirname "$0"`"

# simple forwarder for running tModLoader via steam
bash TerraCustom $@

After that everything works as expected.
Except that selecting Small/Medium/Large in the world size selection before giving the world a name instead of selecting Keep Previous Custom Size, ignores the world parameters set in the following configuration part. That was not expected.
