ThemeSel is Themes and FontSel is Fonts; the old words still work in init files and dumps

The user asked for the plainer words. Every use is renamed: the
builtins, leader paths, /commands, the docs and tutor, tests, and the
themesel golden, re-recorded. An init file's ThemeSel or FontSel runs
the new word and says `ThemeSel: renamed to Themes`, as ColumnTags is
said; a dump naming an output pane by the old word restores it.
