Play a mod using GenLauncher

[prettyblueberry]

Now the repo is growing fast and as a fan of Generals mod, I want to test this improved version playing mods like TEOD or ROTR.

I replaced generals.exe and modded.exe in working genlauncher directory, but the genlauncher didn't run a mod correctly.

I'm trying to use builds from https://github.com/fbraz3/GeneralsGameCode/releases
The repo is a fork to make preview releases.

1. You do not need to use forks to get the latest executables, they are generated for every commit. For example, you can find the latest commit versions at the bottom of the page here
2. This works fine for me. Copy over latest generalszh.exe, rename it to modded.exe (backing up GL version), turning off 'use gentool' and turning on 'use modded exe' in GL settings, then you can run mods as usual.
