Included sheet.json and preview image

Preview is of *current* sheet, not final product. The existence of
sheet.json is not an indication of preparedness to submit to the yaml,
so it has been renamed sheet.json.INCOMPLETE.
Cleaning master

Until this project is ready for final submission, exalted2e.jpg and
sheet.json should stay OUT out the master branch. Updates to them should
be placed in the do-not-pull branch.
Updates to rolls, ready for template.

The AD&D2E sheet now has updated roll buttons, and buttons for each
weapon slot and proficiency slot. It's also been prepared for
availability as a standard template.
