I've added the feature no one asked for. Ever.
-Added a Half-Life: Source mod template.
Also, in this patch, there were the following fixes:
-Fixed bad Team Fortress 2 compile tools (Thanks, @Flatbread).
I'm improving how the tool recognizes engine branches, to properly support Portal 2 and Garry's Mod in the future.
Portal 2 uses Hammer++ if CSGO Authoring Tools is installed. I'll use this method to have Garry's Mod use Hammer++ if Source SDK 2013 Multiplayer is installed.
The updates should be applied seamlessly. If not, or if you don't have the tool yet, you can download it here:https://modding-assets.net/items/source/tools/modding/xblah-modding-tool
