!!psr Plugin

[Nessworthy]

!!psr [<number>|list [accepted|review|draft|deprecated]]

E.g.:

!!psr 4

[psr-4](http://www.php-fig.org/psr/psr-4/) - This psr describes a specification for autoloading classes from file paths.

Individual psrs might have to be hard coded, because the PHP-FIG is a fickle beast that can't seem to draw up a standard way of writing psr documents, but the lists can be read from http://www.php-fig.org/psr/.

Links to individual psrs always follow: http://www.php-fig.org/psr/psr-x only for accepted & deprecated psrs, otherwise they're over in https://github.com/php-fig/fig-standards/tree/master/proposed/. Joy.

Future development could add term linking, e.g. !!psr autoload would return info about psr-0 and 4 (or just 4)
