Summary:
This is in preparation for getting the "View Options" dropdown working on audits.
- Use Files to serve raw data so we get all the security benefits of the alternate file domain. Although the difficulty of exploiting this is high (you need commit access to the repo) there's no reason to leave it dangling.
- Add a "contentHash" to Files so we can lookup files by content rather than adding some weird linker table. We can do other things with this later, potentially.
- Don't use 'data' URIs since they're crazy and we can just link to the file URI.
- When showing a binary file or an image, don't give options like "show highlighted text with blame" or "edit in external editor" since they don't make any sense.
- Use the existing infrastructure to figure out if things are images or binaries instead of an ad-hoc thing in this class.
Test Plan: Looked at text, image and binary files in Diffusion. Verified we reuse existing files if we've already generated them.
