Vim visual block mode

Browse source 
This isn't quite an exact emulation, as instead of using one selection
that is magically in "column mode", we emulate it with a bunch of zed
multi-selections (one per line).

I think this is better, as it requires fewer changes to the codebase,
and lets you see the impact of any changes immediately on all lines.
