[PATCH] rcfile: introduce nine new named colors, from "pink" to "latte"

[Benno Schulenberg]

Names give a rough idea of what the color will look like, whereas
numerical indexes would not do this at all.

Nine extra colors seems enough.  If there were more, no one would be
able to say for sure which is which when two similar colors are used
several characters apart.

This partially fulfills https://savannah.gnu.org/bugs/?56445.
