The time/allocation profile now shows costs as both

	- "individual" (incurred by the specific cost-centre stack), and
	- "inherited" (incurrent by the cost-centre stack and all its
	  children).

In addition, the "inner" column has been removed (should be the same
as the sum of the scc counts of the children of the current node), and
the "caf" column has been removed (wasn't very useful).
