This commit fixes an issue we had with adding a Filter Action to Send an Email. We had an option at the top for 'Default System Email', however, it did not have the Email ID or address for the system email and would throw an error if chosen. Now, we just retrieve the emails with their IDs and values with the Default System Email being the initial value selected in the list of options.

This commit fixes the way we validate filter actions before saving a filter. Now, the code will accurately validate the action without needing a filter_id first while making sure all validations stay withing the validate_actions function.

Fix case where filter applying 'Use Reply-To Email' filter action
triggers a reprocessing loop that exhausts php memory.

This is my attempt at removing similar texts from the translator work load.
It also makes an attempt at dropping some misspelled words and works toward
standardizing some phrases.

Require subject and message go send mail filter action

Action to disable auto-autoresponse doesn't require  any config check.

* Set all "route department" filter actions to "unchanged"

Add ability to extend Form
Support the concept of form ID
Clear/hide field errors on blur

  * Add trashcan icon for newly-added actions
  * Categorize filter actions
  * Use imperative phrases for action descriptions
  * Drop check boxes from simple actions (like reject ticket)
  * Hide empty forms on new ticket pages
  * Do not store config for nondata fields for actions
  * Implement a multi-use feature for actions, which will allow using a
    action more than once (for instance, multiple email sends)
  * Filter actions are sortable
  * Send email has from address configurable
  * %{user} token is valid as a recipient

This patch rebases filters into a row-based layout and redesigns the filter
apply method to be more extensible. It also redesigns the UI to be more
dynamic and to allow for actions to be added without database modification
and actions can also have complex configurations.
