Create domain-sensitive input filters

Patch. This has been committed.

The following tasks remain:

* Document the new features.
* Write unit tests for the new features.
* Make the collapsible tips function properly. (See attached)

Tests committed.

Screenshots for use in documentation.

With token filter, you can use [node:url] or similar, can't you? (Maybe not, since you can't specify the path...

I wonder if we can add this via an alter hook to the token_filter() list?

I'd like to keep the domain-sensitive URL filter. I don't like forcing people to install a module for such a small feature.

I am also confused, because the domain tokens don't "work" with Token Filter, which simply says "Global tokens will be replaced with their respective token values (e.g. [site:name] or [current-page:title])."

That doesn't seem very usable to me.

They may _work_, but there is no UI indication that they are available for a node.

On the Domain settings, page, the formatting is lovely, but introduces a dependency on Token module, and it doesn't show the 'current' / 'default' versions of the tokens.

I would (as a user) like to see the available list of tokens on the filter list, not on the advanced info list. (My plan here was to use a collapsible fieldset to show/hide the list.)

Skitch fail.

I would rather have the full list expandable in the help, otherwise, i find it burdensome, but that's not necessarily relevant.

I'm wondering if these lines introduce a Token module dependency, or if this is handled by core.

  $form['domain_classes']['token_help'] = array(
    '#theme' => 'token_tree',
    '#token_types' => array('domain'),
    '#global_types' => FALSE,
  );

Here's a compromise patch which does the following:

* Removes a hard dependency on token.module from the last patch. (Though it's better with Token installed.)
* Changes the url filter string to [canonical-url:path], which is a nice-to-have that I'm going to leave in.
* Runs an update function to replace [current-domain:] with [domain:] in the setting.
* Ensures that [domain:] tokens run properly if $data['domain'] is not provided. (Which can happen in some situations.)

Tests all pass, should be RTBC.

Alright. Fixed and re-committed.
