Support token replacement for block titles

I tried to use this capability with Welcome [user:name] in a block title, and it simply returned the text.

Had to add global $user; to token_block_view_alter(), and change the call to token_replace to $block->title = token_replace($block->title, array( 'user' => $user ), array('sanitize' => FALSE)); to get it to work.

It is necessary to decide which tokens this function should support, and to pass the required $data array to token_replace().

Kudos! I have never had such a rapid response.

Point taken. However, if you are going to restrict the use to system tokens, it might be a good idea to add a token_tree element to the settings. The only list of tokens now available is at admin/help/token.

function token_form_block_admin_configure_alter(&$form, $form_state) {
  $form['settings']['title']['#description'] .= ' ' . t('This field supports tokens.');
  // @todo Figure out why this token validation does not seem to be working here.
  $form['settings']['title']['#element_validate'][] = 'token_element_validate';
  $form['settings']['title']['#token_types'] = array();
  $form['settings']['token_tree'] = array(
      '#theme' => 'token_tree',
      '#token_types' => array(),
      '#weight' => $form['settings']['title']['#weight'] + 0.5,
    );
}

Token validation is not working because the #token_types array is empty, and token_get_invalid_tokens_by_context is bypassed (This might be a bug, since system tokens will never be validated if they are the only context permitted.).

Great module, and thank you for the work you have done.

Thanks again Dave. I've started following the token browser issue.

Node tokens do not seem to be working, but Current Page tokens do.

ex:

[node:title] - not working

[current-page:url:args:value:1] - working

Very cool! Could we make it more easy for site builders to see which tokens are supported?
Looks good with admin theme fix: #1859452: Dialog loads default theme CSS breaking admin theme

#6 Solution works great for me!
[current-user:name] it's enough to do the job in the Block title!
