Add support for Beam, Underline cursors

Notable about this implementation is it takes a different approach for
managing cursor cells that previously. The terminal Grid is now
borrowed *immutably*. Instead of mutating Cells in the Grid, a list is
managed within the RenderableCellsIter. The cell at the cursor location
is skipped over, and instead cells are popped off a list of cursor
cells.

It would be good in the future to share some more code between the
different cursor style implementations for populating the cursor cells
list.

Supercedes #349.
