Fix holdsteady

[bobthedinosaur]

Would it be possible to make the holdsteady tags useful, mainly allow attached units to follow their above hierarchy's rotation, which they currently do not (as I demonstrated in http://springrts.com/phpbb/viewtopic.php?f=11&t=23329 )

Currently hold steady false aligns the attached unit to the map, so when the transport turns (during movement not script) the attached unit remains aligned to the map and rotates inside the transport unit's hierarchy. Why this is even useful, I don't know.

Holdsteady to false, aligns the attached unit to the transports 0 degree heading, and the attached unit will remain that way regardless of any above hierarchy pieces rotating (script wise), but it does stay with the transport alignment as the transport turns during movement. I can see some reasons this may be helpful.

What I and many other modders/ game devs would love to see is either a third option or a fix to holdsteady false, that allows for attached units to be rotated using their transports parts.

Would there be any problems with this?
