Bug Description

We need to make a comprehensive change to the way the gradebook spreadsheet view works, using almost exclusively javascript to render the cells browser-side.

All but one of the cells will be just <td class"cell">score</td>, so the large javascript loop will run quickly. The current cell will be an input field. The event handler for cursor events (and mouse clicks) will change the current cell, turning it into an input field. Whatever the user changes will get sent to the server in the request.

Profiled it a bit. Slowness seems to be caused by:
- overzealous security checks
- complicated/large template rendering
- in some part by data storage/retrieval

Fixed the overzealous security checks. Bug considered fixed, the template rendering slowness should be fixed separately.
