Suggestion: always use token tree dialog

OA contains many modules, fields and content types. This leads to a huge amount of tokens available for nodes and other types. The token tree form element (token_tree) provided by the token module puts information about all tokens in the HTML of the containing page, leading to page sizes of several megabytes. As a performance improvement, a module can request a link to a popup dialog instead. This has to be enabled for each module.

My suggestion is to make this the default using a theme registry alter in oa_core so all token tree form elements use the dialog by default. In this way, not all modules have to make this change individually.

The code would be very concise:

function oa_core_theme_registry_alter(&$theme_registry) {
  if (isset($theme_registry['token_tree'])) {
    $theme_registry['token_tree']['variables']['dialog'] = TRUE;
  }
}

If you like this idea, I'll make a patch.
