Context manager for curses applications. This does a number of
things beyond what curses.wrapper() does.
- Redirect stdout to stderr. This is done so that we can still
use the ncurses interface from within a pipe or subshell.
- Drop the escape delay down to 25ms, similar to vim.
- Remove newline mode.
An ncurses screen is returned by the manager. If any exceptions
occur, all of the setup performed by the manager is undone before
raising the original exception. This should guarantee that any
bugs in the code will not leave the user with a messed up shell.
