list::reframe had buggy behaviour (especially after previous commit). list::reset allows easily resetting the list (cursor = 0, reset frame). list::resize allows resizing the list after a sigwinch more easily. It's a bit of a bitch to get a pretty, non-brutal (without cursor/frame resetting to avoid "jumping" effect) list resize, this algo acheives it somewhat decently and keeps the selected item in a somewhat predictable position.
