Cover every option in the help, the manual and the readme, and say what to install

An audit rather than a feature, prompted by wanting this fit to hand to
somebody else.

Five options had no command-line flag written down in the table the manual
is generated from -- location, hold, schedules, tile_url and speed_unit --
so five flags that exist were missing from the manual.  Four of them did
exist under other names and are now recorded; hold had no flag at all and
has one.

Four switches could be turned off from the command line and not back on:
--no-lookup, --no-basemap, --no-airports and --no-labels had no positive
halves, so an option turned off in the saved settings could not be turned on
again for one run.  All four now have both.

And adsb, which opens the window and draws a map when it stops, could not be
given any of the settings that decide what those look like: no --at, no
--radius, no --tiles, no --map-brightness, no --width, --fps, --trail,
--fade, --stale, --airports or --labels.  It takes all of them now.

The manual had no list of the aircraft options at all -- the ADS-B sections
were hand-written prose -- so five of them appeared nowhere in it.  It now
generates an AIRCRAFT OPTIONS section from the same table the menu and the
flags come from, and the readme carries a table of all thirty-four with
their flags and defaults.  Three tests hold the three of them together: one
that every option records its flag, one that every flag the table claims
actually exists on a command, and one that the readme names them all.

The installing instructions now list every dependency rather than only the
optional ones: the four Python packages with their names in Debian, Fedora
and Arch, and librtlsdr, which is a C library and therefore the one thing
pip cannot bring and a virtual environment cannot supply.  What reaches a
network is written down too -- which host, when, and which file it is cached
in -- since somebody installing this on a metered or air-gapped machine has
to be able to see that nothing is fetched behind their back.  build-repo.sh
needs dpkg-dev and apt-utils, which a minimal system does not have, and now
says so.

Verified rather than asserted: a clean virtual environment, pip install from
this tree, and a real log read back through the installed command.  It pulls
seven wheels rather than the four the page claimed, the other three being
what Rich brings with it.

Also: matplotlib is gone from the readme's dependency table, nothing having
imported it; ffmpeg and Qt are in it, both having been missing; ffmpeg is a
Suggests on the package; and resume.sh is ignored.
