style: small factorisation
Removed duplication of the doc on configuration options.

Well almost, there is still the man and the template conf file, but generating the conf-file would
be a bit overkill
Added an 'align_ops' configuration option

(and reordered the options)
It is now possible to trigger syntax extensions from the config file
Fixed indent of '{' and '[' at EOL
they now behave like '(' which avoids weird results when a line ends with '({' for example
align_params=auto now also aligns after 'match' or 'try'
Fixed strange case with operators and brackets
