#3 group browsers into single (tabbed) window

[Anonymous]

since conceptually all your UIs offer some kind of
information browsing it would be a good idea to merge all
the different windows (hierarchy, queries, context and
so on) in one tabbed window as MSVC does with its own
browsers. I'd like to know that when i need type info i'll
come to this one window instead of chasing one out of
many.
