attack tool tip update

attack tool tip update

• show attacks that cross the current hex, instead of attacks at current point. this makes it easier for these to be displayed.
• display attacks after the unit info, so that it does not hide the unit info when there are many attacks.
• collapse multiple shots with the same weapon type into a single row.
