New unit type: Leader with direct fire capability

[Crossroads]

A placeholder to discuss the new Stu-40 leader with a capability for firing when with another similar unit (ie. someone within range for the attempted hard or soft attack).



Tricky little things. I almost gave up on them already. But will instead do a write up of what I've found out so far for everyone's opinion about them.

Topics to write in more detail later:

- Not selected when firing from the hex: act as regular leaders
- Selected when firing from the hex: participate in volleys and use APs for that too. Curiously, seem to be capable of participating in rounds even when out of AP.
- Seem to be the first to fire
- Seem to be the first to Op Fire
- Can be killed when spotted, while un-spotted units in the same hex (true for regular leaders too)

More to come, stay tuned...
