New Web Epoch Targeting

I've added some code to the system screen in epoch that allows you select a set of ships and then click an enemy. These ships will then attack enemies of this class.

This will allow you interact with a battle in a quicker more stream lined way.

You no longer have to come away from the system report screen you can monitor your units health and now even set targeting.

The check boxes are not used for anything else so that may cause confusion, we'll see what players think.
