Make the column and workspace tags Texts with the pane tag's keys

The headers had their own one-line editor with its own keys: Enter always
executed, h/l and J/K moved between headers and panes, Ctrl-c/x/v cut and
pasted, and TagLine refused a newline that 9P accepted. They are now Texts
like a pane's tag, with no prefix and a default until edited, so normal and
insert mode, undo and the look and execute keys are the body's. Moving
between them is the window keys' job: Up from a pane with nothing above it
reaches its column's tag and then the workspace's, Down comes back, and
Left and Right walk the column tags.
