This is so that we can have -d as an alias for --dot everywhere.
* bin/randaut.cc: Rename -d as -e.
* NEWS: Mention the change.
* doc/org/autfilt.org, doc/org/oaut.org, doc/org/randaut.org,
tests/core/parseaut.test, tests/core/readsave.test: Adjust.
This way -S means --state-based-acc like with other tools
producing automata. This fixes#82.
* src/bin/randaut.cc: Rename -S as -Q, rename --state-acc as
--state-based-acc (with --sbacc as a synonym), and declare -S as the
short version of --state-based-acc.

This implement several new options for --dot in order to
allow emptiness sets to be output as colored ⓿ or ❶...
