Add TUI (text-based user interface) for GHCi debugger
GDB has a really nice TUI mode: https://upload.wikimedia.org/wikipedia/commons/4/47/GDB_TUI.png
It's a curses interface which highlights the line number you're on, and also shows the surrounding lines.
GHCi currently allows stepping through with the :step command, which displays line and column numbers. It would be nice to have some visual indication along with these numbers.
