Issue #2302489 by vijaycs85, jaydub - Small performance change to eliminate repeated variable_get calls.

Issue #2231021 by jaydub: Prevent filtered node or comment title from being added to node or comment edit form.

Changed cache_clear_all() to clear cache_field table when words are added, edited, or removed from the list of words to filter on.

Removed references to language settings for word filters as feature not fully implemented. See https://drupal.org/node/265565

Removed the settings callback for hook_filter_info as there is no actual setting to save, just help text. Moved help text to filter description.

Issue #1738522 by jaydub, Rugman, justingeeslin: Add module enable message with links to configuration pages.
