Previously, there were three different DTDs used. Let's switch to a single one.
We will go with 4.5, since it is latest version that does not have any backwards incompatible changes.
Make synopses more concise in various place, improve
consistency of formatting, and fix some small mistakes
and oversights.

When I decided to add --columns without --show-columns,
I remove the option everywhere. Almost. These are the
leftovers I forgot.

The --verbose and --ostree-verbose options are global to all
subcommands, but --version can only be used with the main "flatpak"
command, so fix the man pages to reflect that.
For a few commands the options aren't fully documented. This commit
makes the manpage documentation (almost) match the options shown
when you run "<command> --help" on the command line.
