Allow changing of curtain wall justification of non type driven curtain walls

[KentBurns]

If you need to lift up the base of a curtain wall, that is not type driven, it will push out all the curtain wall grids by the same amount. Bringing down the top doesn't have the same effect, so it is down to the justification. If we could toggle the justifications of curtain walls, regardless of whether the grid is type driven or not, that would allow large changes to be much faster. We have a building with 35 levels, with a full height curtain wall, and it's a pain.

thanks!
