change the data structure storage to be more logical and efficient 

a complete zonefile can now be described like this:

$zonefile = array('www' => array('a' => array('1.2.3.3', '1.2.3.4')),
                  '@' => array('SOA' => array('hostmaster' => 'localhost', 'email' => 'admin.localhost', 'serial' => '2010082301', 'refresh' => 21600 3600 604800 86400 )'),
                              'A' => array('1.2.3.3'),
                              'MX' => array('mail.localhost'),
                              'NS' => array('localhost', 'ns2.localhost'),
                              )
                 );

i had to change the provision storage class to merge with existing
records in some cases for that to work.

2. there's a duplicate serial in PHP storage (patched?)
3. the internal data structure is confusing and not efficient. here's
a proposed change:
$zonefile = array('www' => array('a' => array('1.2.3.3', '1.2.3.4')),
'@' => array('SOA' => array('hostmaster' => 'localhost', 'email' => 'admin.localhost', 'serial' => '2010082301', 'refresh' => 21600 3600 604800 86400 )'),
'A' => array('1.2.3.3'),
'MX' => array('mail.localhost'),
'NS' => array('localhost', 'ns2.localhost'),
)
);
(patched, needs testing and verification)
4. removing the last record in a zonefile doesn't remove the zone
5. removing records doesn't work either
6. we increment the serial in two places, it seems
Caveats: Caveats:
1. only targeting bind right now 1. there's duplicate storage altogether: we could parse zonefiles and
use that as storage, not PHP files, but that would make switching
engines more difficult and would require writing parsers for all
engines.
