Fix cursor color setting with escape sequence

The cursor rework introduced a regression where cursor color was always picked
from a config file, rather then using `ansi::NamedColor::Cursor` for this
purpose.

This commit also removes `CursorText` option from `NamedColor` enum,
since we can't speculate with `CursorText` during runtime.
