submissions#show issue where 'edit content' would block link

This was because the div was above the image link. Now they are both links. Additionally I shifted the Edit content to center off the size of the image instead of 10px below the top.
Closes #924. Another Devilish Bug Vanquished.
fix screen permission (don't show all screens in other section)

- change block based screen abilities to non-block ones
- use cancan to get accessible screens
only load accessible root feeds

let the database do the hard work
only load submittable feeds from database

- copy submission creation rules to custom feed submit action
