* Improve documentation with command lines and defaults.
The advanced documentation coverage skipped the simple approach and didn't
explain fully what to do with the sample commands.
Fixes#1413.
* Fix docs indentation in the MySQL connection string options.
* Desultory docs and docs config fixes.
The option "fields optionally enclosed by" was missing a way to easily
specify a single quote as the quoting character. Add '\'' to the existing
solution '0x27' which isn't as friendly.
See #705.
The website is moving to pgloader.org and readthedocs.io is going to be
integrated. Let's see what happens. The docs build fine locally with the
sphinx tools and the docs/Makefile.
Having separate files for the documentation should help ease the maintenance
and add new topics, such as support for Common Lisp Hackers level docs,
which are currently missing.
