Splitting the screen

Would help a lot for repl-driven coding workflow

mentioned in issue #127 (closed)

mentioned in merge request !31 (merged)

This works but is pretty sketchy and experimental.

Right now you have to invoke it in a very awkward way, and it only splits vertically in half. We need functions to change the active buffer.

Splits are currently invoked like so for a triple split:

split = function()
   local w,h = ship.ui.get_screen_size()
   ship.editor.set_splits({[{10,10,w/2-10,h}] = "current",
         [{w/2+10,10,w/2,h/2-10}] = "*console*",
         [{w/2+10,h/2,w/2,h/2}] = "last"})
end

Editor specific stuff can be tracked in Polywell.
