rcfile: introduce the modifier 'italic', for slanted text

The modifier has to come before the foreground color name, separated
by a comma, and after 'bold,' (when present).  This has no effect on
terminals that are incapable of cursive text, like the Linux console.

This fulfills https://savannah.gnu.org/bugs/?56525.
