This patch converts the central file and threading classes over to use the
ORM.

Key permissions definition array
Move canned and faq permissions to their respective classes.

Allow usage of something like `%{ticket.user.organization.var}`

Conflicts:

	include/i18n/en_US/form.yaml
	include/staff/templates/dynamic-field-config.tmpl.php
	include/staff/ticket-view.inc.php
	include/staff/tickets.inc.php
	scp/js/scp.js

And allow for @context to add context to the bare string literal. For
instance,

    /* @trans, @context "noun" */ 'Open'

Would mark the string 'Open' translatable with context "noun".

Add other locations as well a failsafe for the htmlentities() call

Auto assign tickets to organization's account manager only if the flag is set and as
the last resort i.e topic or filters assignment takes precedence.

Allow developers to specify a sorting position for groups of fields
selectable in the criteria select drop-down

Make the organization page happy!

Use .domain.tld to accept all subdomains of a parent

This is a slight edit over the previous implementation of the same feature.
Previously, an "account" was required, which implies a user account with a
password. This implementation simply requires a user record. Importing of
users by organization domain is still supported -- even if the user does not
yet exist.

Previously we required an account to associate a user to an organization.

Deleting an organization with users will simply orphaned the users.

Don't save 'name' as dynamic data for organization form.

Add organization class
