Some suggestions regarding mostly PVE

Hello everyone,

Here are some suggestions/improvements, some may be harder than others to implement

1) Enable renaming for capitals (I cannot seem to be able to do it via the "usual way")
2) When you move a building in your capital, you obviously cannot put it on top of another one. But you also cannot put it instead of its last position (you have to move it elsewhere then put it near its original position).
3) This may be overpowered, I'm not sure, but maybe let people equip gear on Special Units (such as Somatophylax and so on)
4) Related to "3" but maybe add Special Units to Norse and Babylonian civilizations.
5) Add an "auto stack" button for the inventory (or activate auto stack by default )

Thank you
