ThemeSel in sections: acme and lapis with the current themes, helix and dark as legacy, a section per ported family

The picker's headings come from colors.theme_groups instead of one split at
native_theme_count, so acme (current, matched to plan9port acme's source)
no longer sits under a legacy heading. Ring order follows the sections:
the fifteen pardes palettes, acme, lapis, the faithful ports a family at a
time, then helix and dark, then the imports. An imported theme whose name a
port takes gets _helix, as zed's carry _zed.
