This patch allows some basic support for battalions-like formations:
- A formation will be selected/highlighted in whole by default.
- A player can disable this behaviour by using a hotkey.
This is just to reduce micromanagement, nothing more, nothing less. But it could well be extended and used beyond that! I hope people can use this as a base if they want battalions.
Many thanks to @Angen en @Yves for their mods with battalions, I got much information from those :)
