Resolve Issue #19

The Issue was on line 92 of edit_page.php

Original:
<input name="seo_name" id="seo_name" type="text" value="<?php if
(isset($_GET['page'])) echo $_GET['page']; ?>" />

When I changed to this it was solved:
<input name="seo_name" id="seo_name" type="text" value="<?php if
(isset($_GET['page'])) if (isset($seoname)) echo $seoname; else echo
$title; ?>" />

I added $seoname in the save_page function on line 655:

$data = '<?php'."\n"
.'$title = \''.sanitize($title).'\';'."\n"
.'$seoname = \''.sanitize($seo_title).'\';'."\n"
.'$content = \''.sanitize($content, false).'\';'."\n"
.'$hidden = \''.$hidden.'\';';
