Subject: [PATCH] remove client-side file size caps on upload

The 20/50/10MB upload limits were left over from early development and
are no longer needed.

1. Drop the 20MB maxFileSize prop and check from the chat FileAttacher
2. Drop the 50MB check from the sidebar project-document upload
3. Drop the 10MB check and stale "Max 50MB" hint from the upload dialog
