Revert "vis: clean up interaction between vis and ui"

This caused issues on OpenBSD where it crashed the terminal.
Also on Mac OS X suspend via ^Z (Ctrl-Z) was missing a \r i.e.
the shell prompt was not properly redrawn.

While in principle user interfaces should not have to depend on
libtermkey, in practice this won't be an issue unless we are
adding a non-terminal based UI (which won't happen anytime soon).

This reverts commit 8f92b98848f9366e78c7aa824615bade83971513.

Close #311
