adapting to EE3

Hi!
You need to create addon.setup.php file with content:

<?php
return array(
'author' => 'David Dexter',
'author_url' => 'http://codesly.com',
'description' => 'Creates a simple snippet from a block of text. Please report any issues to https://github.com/dpdexter/snippet/issues',
'name' => 'Snippet',
'namespace' => 'Snippet',
'version' => '3'
);

and remove this from pi.snippet.php:

$plugin_info = array(
                    'pi_name'           => 'Snippet',
                    'pi_version'        => '2.3.1',
                    'pi_author'         => 'David Dexter',
                    'pi_author_url'     => 'http://codesly.com/',
                    'pi_description'    => 'Creates a simple snippet from a block of text. Please report any issues to https://github.com/dpdexter/snippet/issues',
                    'pi_usage'          => snippet::usage()
                );

this is it
Tested on 3.0.1. All working fine
