Content editor tabs feature Orchard

In some circumstances you have so many parts and fields, the content editor of Orchard CMS will become a bit messy.
That's why I've made some changes to the Core of Orchard, so that  you can create tabs for each contenttype and the parts and fields up under those tabs.

Warning: This feature is not yet availble in core because it has to be discussed during the meeting and later on approved on quality.
You can see my results in the following screenshots:

Go to Edit Content Type and see the new button "Edit Tabs:"

Navigate to "Edit Tabs" so you can create and manage tabs for the specified content type:

After saving the tabs you can go to "Edit Placements" and reoder the parts and fields in the created tabs.

Now go edit a content item of specified content type and see the tabs!
