FreeNAS Code

First step for #622.

As of now a superuser is able to login without asking for a password
as long as the password field is set to '!' (UNUSABLE_PASSWORD)

The next step is to warn the user about it so he _will_ change the
as soon as possible. An possible solution is using the new alert system
(currently used for volume status only)

fix a case for zpool status parser when you've got "stripe" of single disks (not vdevs)

added checkbox to 'Export' button to perform a destructive action
- This would give the user more opportunity to recover data
- As a next step the current destroy button as we know it should be removed

This changeset is described in #625 (delphij)

add a checkbox to admin password form change asking whether the root password should be changed as well

Auto-Commit of i18n data from Pootle for GUI

Remove unused imports.

Don't assume diskinfo returns the right values.

Split volume delete method into two steps.

Fixes ticket 623.

(Why cascade removal of shares is an option by the way?)

Modified to reflect the changes in the AD/LDAP code.

Active Directory Now supports child domains, similar LDAP functionality should probably be added.
