API for selection of tab would be nice

[pavel-krivanek]

When debugging, it is sometimes useful to open inspectors during program execution. Now, there is no API to select what tab should be visible by default so hacks like

object presenter millerList pages first trySelectAnyPageWithName: {'Bounds and predictions'}.

are needed.

Note: trySelectAnyPageWithName: is not really good name because it expects a collection of names.
