tui: Improvements to RGB colour support.
The details are in the on-line help under :help true-color .
The brief precis is that nvim is (I hope.) converging with tmux and libvte.
It is taking the same approach with setrgbf and setrgbb terminfo capabilities
that it does with the Ss and Se terminfo capabilities.
