follow the slowest unit in a group

[sanslash332]

Add the option (or add as a default behavior of a group) that when are various units in a group, when you move the group, they move at the same speed of the slowest member of that group.
With that you can keep your formations

To avoid surprises, maybe this would only be the case with units in the same group (defined by control+6, 7, 8 or 9). Units with different orders would be automatically detached from the group.
If an enemy is present, I guess a knight should move at max speed.

Ofcourse, the move at same speed isn't for attacks, is only for a move instruction.
When the units change to attack mode, they will move at their max speed. 📦 Respecting the groups, yep, i agree.
