Weapon & Ballistics stream

[rurounijones]

Some users have asked us to include a way to stream weapons and ballistics.

Opening this issue for discussion. Two options I see.

1. Add weapons to the unit stream.
2. Have a separate weapon stream.

Advantage of having separate streams is no unecessary extra work that might not be used by clients (e.g. OverlordBot does not care about weapons).

No strong opinion from my side, just a remark: If (1), I'd say that we'd have to add a filter property to the units stream to allow filtering the kind of data that is requested. Advantage of (1) is that the weapon/ballistics updates are already ordered with the unit updates.
