Change metabox priority/position

This plugin uses the edit_form_advanced and edit_page_form hooks to add the excerpt editor, rather than a metabox, so the position on the editing page is fixed. Please see trac ticket http://core.trac.ww.wp.xz.cn/ticket/19173 for a discussion about this, or the notes section of the Codex page for wp_editor. I am currently testing a version which can be placed in a metabox using a modified script from the trac discussion – there are still issues with it though, and I will probably release it in version 1.3 as a configurable option.

This has now been fixed in the plugin and you can now add the excerpt editor as a draggable, sortable metabox, or in a fixed position as before. This involved adding some script from the trac ticket I mentioned above which fixes the issue with TinyMCE in a draggable box. I have kept this as a configurable option, because I’m not able to test in all browsers.
