Fire on_pre_built Before Fluid Mixing Check

[MrGrim]

It's been said before that on_pre_built is intended to be called even when a build action doesn't happen, e.g. here: viewtopic.php?p=534859#p534859

With that in mind, please call this event before the fluid mixing check. It would allow me to take actions to prevent the mixing that would allow the build to ultimately succeed, such as replacing the conflicting entity or entities.

Thanks!

Build checks typically happen client side and so never reach the game state where an event would be possible. So this is simply a can't-implement.

Such is life. Thank you for looking into it.
