Plugins can send usage data

They just need to register to the PLUGIN_USAGE_DATA event, and then to add
either a simple string, or an array of key / value. For example:

    function register(Doku_Event_Handler $controller) {
      $controller->register_hook('PLUGIN_USAGE_DATA', 'AFTER', $this, 'usage_data');
    }

    function usage_data(&$event){
      $event->data['my_plugin_name'] = 'my usage data';

      //or: $event->data['my_plugin_name'] = array ('k1' => 'v1', 'k2' => 'v2');
    }

To negate a config value, prefix the value with an '!'.

E.g. to disable recognition of the gopher scheme
!gopher

This applies to:
- scheme
- stopwords

This applies to:
- acronyms
- entities
- interwiki
- mime
- smileys

This was previously carried out in three separate places. Refactor
that code to use the new function.
