Title: make paste focuses the pasted cell

This is to make paste behave in the same manner that insert cell above and
below currently work (inserting a new item causes that item to receive focus).

This solves a problem where, if a user pastes below a cell whose bottom edge
is below the current viewing area, they have no indication that any action has
occurred. The same applies for paste above a cell whose top edge is occluded.
