File Upload and Rulebook Fixes

File Uploads

1. Added a new “Revalidate” upload option so file overwrites tell clients to revalidate cached versions. On by default to make sure latest images are seen.
2. Added a new "Preserve Original" upload option so the original file doesn't get deleted, incase you want to offer a fallback for older ios browsers that don't support webp format.

Rulebook Component

1. Rulebooks now have Right Click -> Component -> Edit/Save/Load Component options. They will also get picked up by the Resync button.
2. More rulebook component polish and in-modal page additions coming in another update very soon.
