Add control over if loads should be using dependency types and if bar end node comparer should be used

[IsakNaslundBh]

Description:

Need to be able to control if the dependency types for loads on elements should be on or not. Would default to turning them off to align with workflows of other toolkits. Keeping them on makes pushing loads take a significant time on larger models.

Also, need control if the Bar comparer should be used. It can be dangerous as it can silently cull away duplicate bars. Again, will set defaults to false.
