Add settings for external plugins.

Plugins can be used in multiple profiles, but not necessarily in all. Because of that, we need to process plugins for each profile, even if most of their settings are not stored per profile.

Implementations of hook_wysiwyg_plugin() may execute different code for each editor. Therefore, we have to invoke those implementations for each editor, but process the resulting plugins separately for each profile.

Drupal plugins differ to native plugins in that they have plugin-specific definitions and settings, which need to be processed only once. But they are also passed to the editor to prepare settings specific to the editor. Therefore, we load and process the Drupal plugins only once, and hand off the effective definitions for each profile to the editor.

@todo Rewrite wysiwyg_process_form() to build a registry of effective profiles in use, so we can process plugins in multiple profiles in one shot and simplify this entire function.
