Added three new fields, and updated local_classes.php accordingly.

ALTER TABLE `poems` ADD `po_illustrator` VARCHAR( 45 ) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL AFTER `po_origLang` ,
ADD `po_illustrations` VARCHAR( 2048 ) NOT NULL AFTER `po_illustrator` ,
ADD INDEX ( po_illustrator, po_illustrations );

ALTER TABLE `poems` ADD `po_images` VARCHAR( 2048 ) NOT NULL AFTER `po_text` ,
ADD INDEX ( po_images );
