Running / Charging Units

[historic_bruno]

Some outdated info from the design doc about this:

• Melee infantry, cavalry, military ships, and some animals are able to automatically "run" if their target is within a certain min (to stop them from running at someone too close) and max (to stop them from covering great distances) range.
• This includes any form of movement, including both specific commands to move to a location, and when movement is required to reach another target (an opponent to attack, for example).
• If he comes to a halt, reaches his destination, or is commanded to move to a location out of his maximum run range, he'll come out of charge mode and return to normal "walking" movement.
• Units that can run, without the ability to attack (eg deer), just use this as a faster way of getting about, particularly fleeing from attackers over short distances.
• Units without the ability to run (eg ranged infantry, Female Citizens) simply function as normal, always moving at normal speed.
• If a unit attacks another unit while running, and has to stop moving in order to do so (for example, halt to strike an adjacent opponent with a sword), he will drop out of charge mode, but the momentum of his charge will give him a double damage bonus on his first attack.

Also need to implement some hotkeys for running, apparently it was double-right-clicking in the old simulation. The animations speeds will need to be readjusted, since we have been increasing them to compensate for lack of running.
