various improvements for ease of empire management

[siyoa]

Can you make all ground troop types (tanks, marauders and Assault Marines) be always sorted to the end of the planet pop MGMT screen?

It is a recurring bug that these unit types are dynamically sorted during embarking and disembarking troops and thus the player needs to "chase" the icon during this activity Has been resolved a couple of times before but the behaviour always seem to crop up again

I will check it
