0.9.1

Changes since last release (0.9.0...0.9.1)

• SECURITY: we were matching unsafe URL prefixes, such as data: or javascript:, in a case-sensitive manner. This meant prefixes like Data: were untouched. Please upgrade as soon as possible. (Kouhei Morita)
• Add support for ignoring front matter. (#170, Eitan Mosenkis.)

Two new binaries are added to each release: aarch64-apple-darwin and x86_64-unknown-freebsd.
