Custom Font not converting. Fallback required.

[kprovance]

The redux.io website is set to read-only, so the font conversation system is failing. Ideally, the site read/write permissions must be set appropriately to fix this. I don't have the ability or permission to CHMOD the files and folders to their ideal settings.

The custom font extension fails gracefully but doesn't add the user-submitted font. Needs to do that.
