Tower and gate suggestions

[georgir]

Here are a couple of my suggestions for improvements after playing what's available so far:
- Gates seem to have two different sides, front or outside "business end" and back or inside. Orient it appropriately by default instead of always in the same way - use the center of the current camera view relative to the city hall as a hint, and assume the player wants the business end to face away from the city hall.
- It may be just me, but it's not always obvious which side is which. Consider making the business end of its model more obvious. Add some flags or something perhaps?
- When filling gates and towers with troops, right now always its leftmost column is filled first, from back to front. Instead, always fill the "front" row first.
- Since towers are mostly symmetric, and people rarely would bother rotating them, maybe consider "front" the side that's away from the city hall. And/or also auto-orient them when placing like I suggested for gates. And/or add some visual cues for their "front" as well, though that's probably not as good as people will sometimes want them at corners and not want them to look out of place.
- If you decide to take this to the next level, have units only be able to climb or leave towers and gates from the "back" side, and even climb and leave walls only from a connected tower or gate's back side, maybe with gradual movement instead of snapping into place, etc.
- When a tower or gate is selected you show its troops icons grid always in the same orientation no matter how the tower or gate was oriented when placing it, and I think this is confusing. Perhaps try to match the troop grid in the UI with the building orientation. Or add an indicator for North or for the gate/tower's "front" near the troop grid UI.
- When ejecting all troops from a tower or gate, select the ejected troops instead of keeping the selection on the tower. Chances are we are ejecting them to give them some commands, save us the hassle of trying to select them.
- It is not clear to me what clicking on individual troops in a tower, gate or wall does. The clicked unit's icon and the "Move out" command button become faded as if something happened, but what? "Move out" still works the same, ejecting all troops instead of just the selected one. You also can not select a few at once this way. What was intended here?

- Allow mixing of siege weapons and troops on the large tower, i.e. 1+16 or 2+10 or 3+4 (or even 2+8 if we are silly enough to put the siege weapons diagonally instead of next to each other)
