[PATCH] Ranged units need a special melee/knife attack to hunt animals

[historic_bruno]

It's currently too difficult for ranged units to hunt sheep, chickens and lions with their ranged weapons. For hunting non-skittish animals only, we should give them an alternate melee attack as a special case. It should be a particularly effective attack, only one hit should be required to kill most domestic animals.

I'm fairly new to this game so I wasn't sure what to do for the numbers in the xml file... those were taken from template_unit_cavalry_melee.xml for demonstration purposes.

In 12705:

Added a Slaughter attack type which instantly kills all herdable animals with a melee attack. Fixes #1652.

Thank you for the patch. I decided to implement this slightly differently to your patch, adding an extra Slaughter attack type. This allows all units to one hit kill domestic animals.
