This is kinda rough and needs a finishing touch.
- Adds ncurses-specific terminfo entries for modifiers.
- Supports modifiers in the terminal itself.
- Updates the vim config to understand ctrl-arrows.
- Adds limited support for some modifiers in lib/kbd
(as used by rline)
- Adds limited support for Ctrl+Arrows to rline
(needs major improvements, only jumps to spaces)
