Changed error messages:  now don't print anything below main() unless the new
option --show-below-main is on.  It's on by default.  It also affects
suppressions generated with --gen-suppressions=yes.  Updated reg tests
accordingly.

Also updated docs for this.  And added some missing command-line args to docs.
Also compartmentalised the options a little in the docs, and rearranged the
order of options in the usage message, in anticipation of a bigger
rearrangement that will be necessary soon -- to distinguish options used by all
skins from those used by error-checking skins, to skin-specific ones.
