Throttle training in houses when blanks die on their route

[Kromster80]

The "throttle" should be on training house's side, not on the blanks supply (cottages)
[12:36 PM] Krom: and now I kind of see the UI
if blank gets killed, his training bar turns red and fills up very slowly
[12:37 PM] Krom: until that the queue can be changed, but no new unit in this house starts training until red bar fills to full
[12:38 PM] Krom: and ... if in red-bar mode, blanks can turn around and dont walk to that "cursed house that causes death upon them"
[12:39 PM] Krom: this way, all other camps/schools/forts etc won't suffer, cos indeed, enemy got only one of them and others should work and pump out new troops and etc
