implement the more useful normal mode highlightingHEADmaster

This makes use of vis's recursive mappings to call the highlighted-yank
action after some logic to figure out if a complete selection was made.

There isn't a good way of determing the end of the selection after
entering OPERATOR_PENDING mode so we have to check after each keypress
to determine if it can terminate a selection. Some keys might be missing
but all the main ones should be there.
