Changes:

• switched to text/html as the only content type, local XML nbsp and sdot definitions used to break quite often with caching enabled
• stopped revealing the git version
• fixed “Reading blob failed” error false positives
• made file sizes be displayed in a human-readable format
• added ZSTD-compressed tarball snapshot support
• added snapshot links to the project index (requires at least two snapshot formats enabled)
• added support for URIs with no “.git” in the project name
