Module (widget like) Based Write (post/page) screens

[thee17]

I propose we implement a system, possibly AJAX, where the write screens can be configured as module in order and have a box as optionally 100%, 50%, 33% widths.

Allow plugins to add these modules.

Default these to 100%.

Have module sets specific for users.

Allow users or admins not to have a module load on the write screen. (eg disable, custom fields for certain types or certain users.
