Tube&Pipe 101: “Style Editor, replace multiple styles”

[salariua]

In the T&P Style Editor, give us a way of swapping families for multiple styles at once.  We should be able to edit the category folder or select multiple styles and change component families (like changing jus the elbow family).  I want to replace/swap elements (elbow for example) for a whole category rather than editing each and every style individually. If some fail because of missing items (missing family members for the size) then permit the operation but show the style with an exclamation mark and allow us to manually fix it.
