TeamMonitor: Group teams.

Programs like Iceweasel and Falkon/QTWebEngine spawn lots of processes
that clog up Team monitor. To reduce the clutter, group teams under the BApplication that spawned them.

Groups are collapsed by default, and the tree only goes one level deep.
If a BApp spawns other BApps with the same executable, they are grouped
under it.

Also, fix bug where opening Team monitor before be_roster has info for a
BApp (immediately after launch) can sometimes cause the 'Quit' button to
be incorrectly disabled.

Also, update BOutlineListView::RemoveItem documentation; neither the
BeBook nor the HaikuBook mentioned that these will both remove *and
delete* child items (BeBook mentions removing, HaikuBook mentions
neither), which cost me some time debugging . . .

(a previous version of this patch grouped solely by name)
