Debugger: Improve appearance of TeamsWindow insets and spacing.

The buttons are now aligned to the scroll bar and window resize knob,
by using BControlLook::GetScrollBarWidth. (Hmm, perhaps it might make
more sense to just have scrollbar sizes be a kind of insets, which can
be gotten via B_USE_SCROLL_BAR_INSETS, and then drop this extra method
altogether? After all there are a lot of applications which align to
scroll bars...)
