Flags for all garrisonable buildings and units

[temple]

Currently some buildings show flags when units are garrisoned, but others do not (like houses). I think all garrisoned buildings should have a flag, so that it's easy to tell where your units are.

Also, currently siege towers have flags but rams and ships do not. I think it's better to be uniform and have all the garrisoned units display a flag.

Could you make a list ? About ships I think it's because there was a bug which correct me if I'm wrong was only fixed recently by sanderd17

[temple]

I'm not sure why some buildings are garrisonable and others not. For example, you can put one unit in a blacksmith but can't put any in a market. Currently you can't garrison in a dock but I don't see a reason why that couldn't be changed in the future. So it might be best to add a flag to every building? But anyway, I made a list, which could certainly have errors.

As of Alpha25 [25848] only two houses have a garrison flag on their building. A user called Gurken Khan reported the issue via the forum - ​A25 Feedbacks from testing (19/Aug/21).
