Don't change currently selected weapon within alternating group when switching between different weapon groups (but do switch if re-selecting same group).
For example, 4x2 Reaper group (with Missile Rack):
- Fire 2 top, selection moves to third (1 1 2* 2)
- Switch to other weapon group
...
- Switch back to Reaper group, selection is on 4th (1 1 2 2*)
This is inconvenient, because if I fire 2 in a row, I'd end up with (0 1* 2 1), rather than (1* 1 1 1). As result I need to pause and fix selection before firing for optimal result.
